NEW YORK (AP) — New York City Mayor Eric Adams has been indicted by a grand jury on federal criminal charges, according to two people familiar with the matter, an extraordinary culmination to weeks of searches, subpoenas and resignations of top officials that have thrust the city’s government into crisis.

The indictment detailing the charges against Adams, a Democrat, was expected to be unsealed Thursday, according to the people, who spoke with The Associated Press on condition of anonymity because they were not authorized to discuss the matter publicly.

The U.S. attorney’s office in Manhattan declined to comment.

In a speech recorded at his official residence, Adams said he would remain in office, describing any charges he may face as “entirely false, based on lies.”

“I always knew that if I stood my ground for all of you, that I would be a target — and a target I became,” Adams said. "I will fight these injustices with every ounce of my strength and my spirit."

It was not immediately clear what laws Adams is accused of breaking or when he might have to appear in court.

Federal investigators had seized Adams' electronic devices nearly a year ago as part of an investigation focused, at least partly, on campaign contributions and Adams' interactions with the Turkish government. Because the charges were sealed, it was unknown whether they dealt with those same matters.

The indictment was first reported by The New York Times.

It marks a stunning turn for Adams, a former police captain who won election nearly three years ago to become the city’s second Black mayor on a campaign that stressed his working class roots and commitment to public safety. But as Adams has made reducing crime a cornerstone of his administration, he has faced growing legal peril, with multiple federal investigations honing in on his top aides and his own campaign.

In the last two weeks alone, the leaders he appointed to oversee the country's largest police force and largest schools system have announced their resignations.

Adams is the first mayor in New York City history to be indicted while in office. If he were to resign, he would be replaced by the city’s public advocate, Jumaane Williams, who would then schedule a special election.

Gov. Kathy Hochul has the power to remove Adams from office. Hochul spokesperson, Avi Small, issued a statement late Wednesday that said “Governor Hochul is aware of these concerning news reports and is monitoring the situation. It would be premature to comment further until the matter is confirmed by law enforcement.”

The indictment comes against the backdrop of the United Nations General Assembly, which has brought dozens of world leaders to New York, including Turkish President Recep Tayyip Erdogan.

The federal investigations into Adams administration first emerged publicly on Nov. 2, 2023, when FBI agents conducted an early morning raid on the Brooklyn home of his chief fundraiser, Brianna Suggs.

At the time, Adams insisted he followed the law and said he would be “shocked” if anyone on his campaign had acted illegally. Days later, FBI agents seized the mayor’s phones and iPad as he was leaving an event in Manhattan.

Then on Sept. 4, federal investigators seized electronic devices from the city’s police commissioner, schools chancellor, deputy mayor of public safety, first deputy mayor and other trusted confidantes of Adams both in and out of City Hall.

Federal prosecutors declined to discuss the investigations, but people familiar with elements of the cases described multiple, separate inquiries involving senior Adams aides, relatives of those aides, campaign fundraising and possible influence peddling of the police and fire departments.

A week after the searches, the city's police commissioner, Edward Caban, announced his resignation. About two weeks later, Schools Chancellor David Banks announced he would retire at the end of the year.

Adams himself insisted he would keep doing the city’s business and allow the investigations to run their course.

Over the summer, federal prosecutors subpoenaed Adams, his campaign arm and City Hall, requesting information about the mayor’s schedule, his overseas travel and potential connections to the Turkish government.

Adams spent 22 years in New York City’s police department before going into politics, first as a state senator and then as Brooklyn borough president. He was elected as mayor in November 2021 — a victory he has repeatedly said was ordained by God.

But after more than two years in office, Adams’ popularity has declined. While the city has seen an increase in jobs and a drop in certain categories of crime, the administration has struggled with an influx of tens of thousands of international migrants who overwhelmed the city’s homeless shelters.

There has also been a steady drip of accusations and a swirl of suspicion around people close to the mayor.

In addition to the sprawling inquiries launched by Manhattan prosecutors, federal prosecutors in Brooklyn are investigating another one of Adams’ close aides, Winnie Greco, who had raised thousands of dollars in campaign donations from the city’s Chinese American communities and later became his director of Asian affairs. Greco hasn’t commented publicly on the FBI searches of her properties and continues to work for the city.

When agents seized electronic devices from Caban, the former police commissioner, in early September, they also visited his twin brother, James Caban, a former police officer who runs a nightlife consulting business.

Agents also took devices from the schools chancellor; his brother Philip Banks, formerly a top NYPD chief who is now deputy mayor for public safety; their brother Terence Banks, who ran a consulting firm that promised to connect businesses to government stakeholders; and from First Deputy Mayor Sheena Wright, who is David Banks’ domestic partner.

All denied any wrongdoing.

While those investigations churned, federal authorities also searched the homes of newly named interim police commissioner, Thomas Donlan, and seized materials unrelated to his police work. Donlon confirmed the search and said it involved materials that had been in his possession for 20 years.

In his speech Wednesday night, Adams appeared to cite that search as proof of overreach by federal investigators.

Hours before the charges were announced, U.S. Rep. Alexandria Ocasio-Cortez called on Adams to resign, the first nationally prominent Democrat to do so. Adams reacted with scorn, dismissing Ocasio-Cortez as self-righteous.

Adams, who is expecting a tough primary election next year, faced additional calls to resign once the indictment became public Wednesday night, including from many of his declared or expected Democratic challengers in the mayoral race.

Brad Lander, the city’s comptroller, said the indictment marked “a sad day for New Yorkers.” State Sen. Zellnor Myrie added that it was “especially painful for so many Black New Yorkers who put our hope and faith in this Mayor.”

Scott Stringer, a former city comptroller who is expected to run against Adams, said the indictment had left New York City "with a broken down trainwreck of a municipal government."

Joe Borelli, the top Republican in the City Council, who is believed to be eyeing a run for mayor, said he would reserve judgment until viewing the charges.
