(NEW YORK) — Two improvised explosive devices brought to a counterprotest outside Gracie Mansion in New York City Saturday are being investigated as “an act of ISIS-inspired terrorism,” and the two suspects arrested in connection with the incident are facing federal terrorism charges, New York Police Commissioner Jessica Tisch said Monday.
According to a federal criminal complaint released Monday, both suspects openly pledged allegiance to ISIS while in the presence of police, and one suspect allegedly told officers they “wanted to carry out an attack bigger than the Boston Marathon bombing,” which the suspect noted “caused only ‘three deaths.’”
The explosive devices contained the volatile substance triacetone triperoxide, known as TATP, and were made to “injure, maim or worse,” Tisch said of Saturday’s incident.
“These were not hoax devices or smoke bombs. They were improvised explosive devices,” Tisch said during a news conference outside the Gracie Mansion mayor’s residence with New York City Mayor Zohran Mandami, the city’s first Muslim mayor.
One of the devices was ignited and deployed at protesters in a crosswalk on East End Avenue and East 87 Street, and the other device was detonated close by, Tisch said.
Tisch said a third suspected IED was found in the car of the two suspects, a black 2010 Honda with New Jersey license plates, parked on the Upper East Side of Manhattan near Gracie Mansion, prompting an immediate evacuation of homes in the area. She said the device did not test positive for explosives.
All of the devices are being sent to the FBI lab in Quantico, Virginia, for additional testing, Tisch said.
Two Pennsylvania men who are in custody are charged in a five-count federal complaint with attempting to provide material support and resources to ISIS, use of a weapon of mass destruction, transportation of explosive materials, interstate transportation and receipt of explosives, and unlawful possession of destructive devices.
The suspects were identified as Emir Balat of Langhorne, Pennsylvania, and Ibrahim Kayumi of Newton, Pennsylvania, according to Tisch and the federal complaint.
The suspects were ordered to be held without bail after they made their initial appearances, both in shackles, in Manhattan federal court on Monday afternoon. They did not enter a plea to the charges.
“They’re suspected of coming here to commit an act of terrorism,” Mamdani said Monday. “Let me say this plainly: Anyone who comes to New York City to bring violence to our streets will be held accountable in accordance with the law.”
The explosives were deployed at an anti-Muslim protest outside Gracie Mansion that was organized by far-right, anti-immigrant provocateur Jack Lang, officials said. The event was called “Stop the Islamic Takeover of New York City.”
The anti-Muslim protest drew counterprotesters who called their response “Run Nazis Out of New York City,” according to the criminal complaint.
“FBI’s Joint Terrorism Task Force is investigating the matter with our partners at NYPD as well as the U.S. Attorney’s Office for the Southern District of New York,” the FBI said in a statement Sunday.
Balat and Kayumi are suspected of attending the event as part of the counterprotest to the anti-Muslim demonstration, authorities said Monday.
Neither Mamdani nor his wife, Rama Duwaji, were in Gracie Mansion when the incident occurred, the mayor said Monday.
Immediately following his arrest, Kayumi was asked by someone in the surrounding crowd why he allegedly attempted to bomb the protest, according to the complaint.
“Kayumi responded in part and as captured on NYPD body-worn camera footage, ‘ISIS,'” the complaint states.
Balat waived his Miranda rights to remain silent following his arrest, according to the complaint, and allegedly provided a written statement in which he “pledge[d] [] allegience [sic] to the Islamic State,” the complaint states.
Balat also allegedly told police that “they wanted to carry out an attack bigger than the Boston Marathon bombing, which Balat noted caused only ‘three deaths,'” according to the complaint.
The April 15, 2013, Boston Marathon bombing also left more than 500 people injured.
Kayumi, whom the complaint said also waived his Miranda rights, allegedly “stated, in substance and in part, that he was affiliated with ISIS; watched ISIS propaganda on his phone; and was partly inspired to carry out his actions that day by ISIS,” according to the complaint.
“Anti-Muslim bigotry is nothing new to me, nor is it anything new for the one million or so Muslim New Yorkers who know this city as our home,” Mamdani said at Monday’s news conference.
“While I found this protest appalling. I will not waver in my belief that it should be allowed to happen. Ours is a free society, where the right to peaceful protest is sacred. It does not only belong to those we agree with. It belongs to everyone,” Mandani added.
Many of the counterprotesters on Saturday confronted the “display of bigotry,” the mayor said. He also praised NYPD officers who swiftly responded to the incident and arrested the suspects, saying they were “faced with a chaotic situation that quickly could have become far more dangerous.”
The mayor specifically cited the “courageous and selfless” acts of two NYPD officers, Assistant Chief Aaron Edwards and Sgt. Luis Navarro, who attended Monday’s news conference. Mamdani said the officers “ran towards the danger so that others could run safely.”
Tisch said the last incident in New York City in which an IED was deployed occurred in December 2017, when Akayed Ullah detonated a homemade bomb he had strapped to his torso in a pedestrian underpass connecting the Port Authority Bus Terminal to the Time Square subway station.
Ullah, a permanent resident of Bangladesh who was living in Brooklyn at the time, was the only person injured in the act, which federal prosecutors said was committed on behalf of ISIS of Iraq. Ullah was convicted in April 2021 by a federal jury on all six counts of the indictment and was sentenced to life in prison.

(SPRINGFIELD, Ill.) — Sean Grayson, the former Sangamon County sheriff’s deputy, is set to be sentenced on Thursday after his convicted in October 2025 of second-degree murder for the July 2024 fatal shooting of Sonya Massey, a Black woman who called 911 to report a possible intruder at her home in Springfield, Illinois.
Grayson could be sentenced to four to 20 years in prison or he could be sentenced to probation, according to prosecutors.
Sontae Massey, Massey’s cousin, told Springfield ABC affiliate WICS in an interview that aired ahead of the sentencing on Wednesday that her death “shattered” her family and they are now bracing for Grayson’s sentencing.
“I’m a little anxious. I think I speak for the family when I say that. You know, there’s a lot of feelings involved, particularly her children,” Sontae Massey said.
She noted that family members, including Massey’s teenage children Malachi and Summer, are expected to deliver impact statements during the sentencing hearing.
Family representatives for the Massey family told ABC News on Wednesday that the family will hold a press conference after Grayson’s sentencing hearing.
Ahead of sentencing Grayson, the judge denied on Thursday morning Grayson’s request for a new trial.
Grayson’s attorneys filed a motion for a new trial on Dec. 2, 2025, arguing that “several erroneous rulings” “resulted in prejudice to the defendant.”
The motion, which was reviewed by ABC News, cited alleged “errors” that include “incorrectly” focusing on Grayson’s “obligations as a police officer” when determining not to release him pre-trial, as opposed to “the danger he posed as a private citizen.”
Grayson’s attorneys also argued in the motion that the judge should not have admitted into evidence the body camera video that showed Grayson’s “statements and actions” after he fatally shot Massey.
Grayson’s attorneys did not respond to ABC News’ requests for comment.
Sangamon County State’s Attorney John Milhiser, who prosecuted Grayson, told ABC News on Thursday that his office filed a motion asking the judge to deny Grayson’s request for a new trial.
Body camera footage of the July 6, 2024 incident shows Grayson, who was inside Massey’s home, pointing to a pot of boiling water on her stove and says, “Walk away from your hot steaming water.”
Massey then appears to pour the water into the sink and repeats the deputy’s phrase before saying, “I rebuke you in the name of Jesus,” according to the video.
Grayson threatens to shoot her and Massey apologizes and ducks down behind a counter, covering her face with what appears to be a red oven mitt, the video shows. As she briefly rises, Grayson shoots her three times in the face, the footage shows.
During Grayson’s testimony, he told the jury he believed Massey was going to throw the scalding water on him and was scared.
The assistant state attorney said that Massey’s final words before being shot with her hands up were, “I’m sorry,” according to WICS.
Grayson was initially charged with three counts in connection to Massey’s death — first-degree murder, aggravated battery with a firearm and official misconduct. He pleaded not guilty to all counts.
Following the seven-day trial in October 2025, the jury was given the option of considering second-degree murder instead of first-degree murder.

(WASHINGTON) — The Environmental Protection Agency has walked back a landmark environmental decision to regulate greenhouse gas emissions and fight climate change.
Calling it “the single largest deregulatory action in U.S. history,” the EPA announced Thursday that it was “eliminating both the Obama-era 2009 Greenhouse Gas (GHG) Endangerment Finding and all subsequent federal GHG emission standards for all vehicles and engines of model years 2012 to 2027 and beyond.”
For more than 16 years, the EPA’s endangerment finding served as the scientific and legal foundation for federal regulations on carbon dioxide and five other heat-trapping greenhouse gases. The 2009 decision found that certain greenhouse gases endanger public health and welfare. The regulations that resulted cover everything from vehicle tailpipe emissions to the release of greenhouse gases from power plants and other significant emission sources.
EPA Administrator Lee Zeldin made the announcement in the White House, alongside President Donald Trump.
“The Endangerment Finding has been the source of 16 years of consumer choice restrictions and trillions of dollars in hidden costs for Americans,” Zeldin said in a statement after the announcement. “The Trump EPA is strictly following the letter of the law, returning commonsense to policy, delivering consumer choice to Americans and advancing the American Dream.”
The EPA said the decision would “[save] American taxpayers over $1.3 trillion,” and “restores consumer choice, makes more affordable vehicles available for American families, and decreases the cost of living on all products by lowering the cost of trucks.”
In a statement to ABC News prior to Thursday’s announcement, the EPA called the endangerment finding “one of the most damaging decisions in modern history,” adding, “in the intervening years, hardworking families and small businesses have paid the price as a result.”
Some climate scientists and policy experts say the agency’s decision to repeal the finding, even just for cars and trucks, could significantly affect U.S. efforts to address human-amplified climate change. The EPA calculates that the transportation sector is the largest contributor of direct greenhouse gas emissions in the country, with cars and trucks accounting for more 75% of those emissions.
“This is taking away the principal federal authority to regulate greenhouse gases. All of the federal regulations under the Clean Air Act to regulate greenhouse gases depend on the endangerment finding. If it’s wiped out, none of those regulations exist,” said Michael Gerrard, a professor at Columbia Law School and the faculty director of the Sabin Center for Climate Change Law.
Gerrard said the immediate impact of the EPA’s decision will be somewhat muted by the fact that the Trump administration has already revoked most regulations on greenhouse gas emissions. These include greenhouse gas emission limits on passenger vehicles, emission controls on fossil fuel-powered power plants, and controls on methane leakage from oil and gas wells.
“But this action attempts to be the nail in the coffin of all those regulations, at least for the balance of the Trump administration,” Gerrard added.
Saying the decision “amounts to the largest act of deregulation in the history of the United States,” the Trump administration estimates the move will save Americans $1.3 trillion, primarily by reducing the cost of cars and trucks. The EPA said consumers will save more than $2,400 on the purchase of a new vehicle.
But Lou Leonard, dean of Clark University’s School of Climate, Environment, and Society, says the repeal could also result in companies facing more financial and legal challenges.
“It’s going to expose, particularly businesses that are very fossil fuel intensive, to legal claims that they might not have otherwise been exposed to,” said Leonard.
“When the EPA vacates the space legally and says we’re not going to regulate, we’re out of this game, then that not only creates room for other state and local governments to do their regulation, but it also creates room for legal claims against companies for not acting on climate, because they can’t say, well, we’re just following the regulations that the federal government has created,” he added.
“The EPA’s 2009 endangerment finding triggered a trillion-dollar regulatory cascade that Congress never authorized,” the conservative nonprofit Pacific Legal Foundation said in a statement to ABC News. “What began as authority to address regional smog and acid rain has been stretched to vehicle emissions, power plants, oil and gas operations, and federal lands – reshaping America’s entire energy economy and ability to harness natural resources through administrative fiat.”
The EPA’s expected repeal of the 2009 finding “restores the principle that decisions of this magnitude require clear congressional authorization, not bureaucratic improvisation,” the statement continued.
A widely anticipated decision
The announcement from the administration was widely anticipated; the Trump administration has made the endangerment finding’s review a priority since the first day of Trump’s second term.
On Jan. 20, 2025, Trump signed an executive order titled “Unleashing American Energy” that required the head of the EPA to work with other agencies to “submit joint recommendations to the Director of OMB on the legality and continuing applicability of the Administrator’s findings” regarding the endangerment finding. The order gave them 30 days to respond.
Then, in March, the EPA announced more than two dozen policy recommendations aimed at rolling back environmental protections and eliminating a series of climate change regulations, including plans to “formally reconsider the endangerment finding.”
In a statement at the time, EPA Administrator Lee Zeldin wrote, “The Trump Administration will not sacrifice national prosperity, energy security, and the freedom of our people for an agenda that throttles our industries, our mobility, and our consumer choice while benefiting adversaries overseas. We will follow the science, the law, and common sense wherever it leads, and we will do so while advancing our commitment towards helping to deliver cleaner, healthier, and safer air, land, and water.”
As part of the March announcement, the agency released a fact sheet about the endangerment finding, describing it as “the first step in the Obama-Biden Administration’s (and later the Biden-Harris Administration’s) overreaching climate agenda” and stating that it has cost the country trillions of dollars.
The EPA announced its proposal to rescind the endangerment finding in late July 2025, citing recent Supreme Court decisions that limited the regulatory power of executive agencies and arguing that the Obama administration misinterpreted Congress’s intent when it passed the Clean Air Act.
The Supreme Court case that led to the endangerment finding
The endangerment finding stems from the 2007 Supreme Court decision Massachusetts v. EPA, which held that the EPA could regulate greenhouse gases from motor vehicles under the 1970 Clean Air Act because those gases are air pollutants.
That ruling became the legal foundation for many of the federal government’s greenhouse gas emissions regulations for vehicles, fossil-fuel power plants, and other sources of pollution responsible for climate change.
Writing for the court at the time, Justice John Paul Stevens said, “If EPA makes a finding of endangerment, the Clean Air Act requires the agency to regulate emissions of the deleterious pollutant from new motor vehicles.”
“Under the clear terms of the Clean Air Act, EPA can avoid taking further action only if it determines that greenhouse gases do not contribute to climate change or if it provides some reasonable explanation as to why it cannot or will not exercise its discretion to determine whether they do,” Stevens added.
In 2009, the head of the EPA made a landmark environmental decision. Lisa P. Jackson, appointed by President Barack Obama to lead the agency, determined that the current and projected concentrations of six greenhouse gases, including carbon dioxide, “endanger both the public health and the public welfare of current and future generations.” Her decision, based on a nearly 200-page EPA analysis of the science, more than 380,000 public comments and two public hearings, became what is now known as the “endangerment finding.”
Critics of decision say the underlying science is even stronger today
Critics of the administration’s plan to rescind the finding argue that the science linking greenhouse gas emissions to climate change is even stronger today than when the endangerment finding was established in 2009. They argue that the repeal lacks both a scientific basis and a legal foundation and will exacerbate the harmful impacts of climate change. Some are already promising to fight the decision in court.
“The Trump administration justifies this assault on science and our health by falsely claiming that U.S. climate-heating pollution doesn’t matter and that it lacks the authority to cut it. That’s a lie, and any 6-year-old knows it’s wrong to lie,” said Dan Becker, director of the Center for Biological Diversity’s Safe Climate Transport Campaign, in a statement to ABC News.
“The United States is the second-largest carbon polluter in the world after China, and the largest historical emitter of greenhouse gases. The U.S. emitted 11% of the world’s greenhouse gases in 2021, and during Trump’s first term his administration admitted that emissions in excess of 3% were ‘significant,’” he added.
“EPA’s own settled science shows that managing greenhouse gases is fundamental to protecting Americans. Rolling back these safeguards is a dangerous breach of responsibility to protect people, the environment, and our economy, benefitting polluters at the expense of all people,” said World Resources Institute (WRI) U.S. Director David Widawsky in a statement.
Overwhelming scientific evidence
In the more than 16 years since the EPA issued its 2009 endangerment finding, the science on how greenhouse gases impact human health has become more robust.
In response to the EPA’s request for public input, the National Academies of Sciences, Engineering, and Medicine conducted a comprehensive independent assessment of the science behind the endangerment finding to help inform the agency’s final decision. They released their report in September, concluding the EPA’s 2009 determination was accurate and is now supported by stronger scientific evidence, with many uncertainties that existed at the time now resolved.
“[T]he evidence for current and future harm to human health and welfare created by human-caused greenhouse gases is beyond scientific dispute,” the report stated.
The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide independent, objective analysis and advice to the nation on such issues. They operate under an 1863 congressional charter to the National Academy of Sciences, signed by President Abraham Lincoln.
Similarly, the United Nations concluded that “health and the climate are inextricably linked, and today the health of billions is endangered by the climate crisis.” The U.N. cited severe weather events, toxic air pollution, an increased risk of infectious disease outbreaks, and extreme heat as evidence that human-amplified climate change poses a significant danger to people.
In 2021, 200 leading medical journals issued a joint editorial stating that “the science is unequivocal: a global increase of 1.5° C above the pre-industrial average and the continued loss of biodiversity risk catastrophic harm to health that will be impossible to reverse.”
And in 2023, the Fifth National Climate Assessment, a report that the federal government describes as providing “authoritative scientific information about climate change risks, impacts, and responses in the U.S.,” found that “climate changes are making it harder to maintain safe homes and healthy families; reliable public services; a sustainable economy; thriving ecosystems, cultures, and traditions; and strong communities.”
“This is another setback in the fight against climate change. We’re already seeing climate change having very negative impacts. It worsens flooding, heat waves, wildfires and other impacts. We’ve seen catastrophes already in the United States for all of these. We will see more,” Gerrard said.
What happens next?
A coalition of state attorneys general, including those from California, New York, Connecticut, and Massachusetts, along with environmental groups such as the Natural Resources Defense Council, has indicated they will challenge the EPA’s decision. They argue the action is unlawful because it ignores the agency’s obligations under the Clean Air Act to regulate pollutants that endanger public health and welfare.
“This action is unlawful, ignores basic science, and denies reality. We know greenhouse gases cause climate change and endanger our communities and our health – and we will not stop fighting to protect the American people from pollution,” said California Governor Gavin Newsom and Wisconsin Governor Tony Evers, who are also the co-chairs of the U.S. Climate Alliance.
While the courts could overturn the repeal, Gerrard said they could also rule that the EPA needs congressional authorization for significant regulatory actions.
“If the Supreme Court says that, that would tie the hands of another president in reinstating the endangerment finding and in using the Clean Air Act to regulate greenhouse gases. It would not block another president from rejoining the Paris Agreement or doing lots of other things to fight climate change, but it would greatly hurt their ability to use the Clean Air Act,” said Gerrard.
Previous lawsuits challenged the endangerment finding itself, but the courts have consistently rejected those efforts. In 2012, the D.C. Circuit Court of Appeals upheld the endangerment finding after fossil fuel industry groups challenged the EPA’s use of scientific assessments. The court ruled that the EPA’s findings were supported by substantial evidence and that the agency had considered the scientific evidence in “a rational manner.” The following year, the Supreme Court declined to hear petitions specifically contesting the finding.
Leonard warns that it will be a “long road” to learn out how the decision plays out.
“There’s a lot of uncertainty, and we’re gonna have even more starting tomorrow or the next day, and that’s not good. It’s not good for the public health of Americans, it’s not good for the welfare of our communities, and it’s not good for the business climate and the economy in America,” said Leonard.
(SEATTLE) — Police in Seattle have arrested a 21-year-old man armed with a shotgun, pistol, and carrying multiple rounds of ammunition near the Space Needle during Seattle’s New Year’s Eve celebration, authorities said.
On New Year’s Eve at approximately 7:20 p.m., patrol officers in Seattle responded to reports of a man sitting on a bench near the Pacific Science Center holding a partially concealed shotgun, according to a statement from the Seattle Police Department.
“Witnesses saw him holding the gun by the grip, causing alarm, while facing the area where spectators were gathering for the fireworks display,” police said. “The suspect, wearing all black clothing and a red hat with “WAR” written on it, cooperated with police.”
Officers safely recovered the shotgun and the suspect, who was also armed with a handgun, had a valid concealed carry permit, police said.
Police assigned to the event center arrested the man without incident, authorities said.
Seattle Police Department’s arson bomb squad were able to locate the suspect’s vehicle and swept the car for potential weapons or explosives, though none were found and it was determined the vehicle did not pose a threat, officials confirmed.
Police subsequently booked the suspect into the King County Jail for unlawful use of weapons and detectives reviewing the case referred criminal charges to the City Attorney’s Office, authorities said.
The investigation into the incident is currently ongoing.
