New York City Mayor Eric Adams was indicted Thursday on federal charges alleging that he took bribes and illegal campaign contributions from foreign sources.

The U.S. attorney's office in Manhattan alleges in the indictment that Adams "compounded his gains" from the illegal contributions by gaming the city's matching funds program, which provides a generous match for small dollar donations. His campaign received more than $10,000 in matching funds as a result of the false certifications, according to the indictment.

Adams allegedly "solicited and demanded" bribes, including free and heavily discounted luxury travel benefits from a Turkish official, the indictment alleges, noting that the official was seeking Adams' help pertaining to regulations of the Turkish consulate in Manhattan.

FBI agents entered the mayor's official residence and seized his phone early Thursday, hours before the indictment was made public.

"Federal agents appeared this morning at Gracie Mansion in an effort to create a spectacle (again) and take Mayor Adams phone (again)," Adams' lawyer, Alex Spiro, said in a statement hours before the indictment was made public. "They send a dozen agents to pick up a phone when we would have happily turned it in."

In a video speech released Wednesday night, Adams vowed to fight any charges against him, claiming he had been made a "target" in a case "based on lies."

"I will fight these injustices with every ounce of my strength and my spirit," he said.

The U.S. attorney's office in Manhattan has declined to comment on the investigation, though it said it would announce "significant public corruption charges" at an 11:30 a.m. news conference. An FBI spokesperson declined to comment. A spokesperson for the mayor did not immediately respond to questions Thursday morning.

Gov. Kathy Hochul has the power to remove Adams from office. Her 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 caps off an extraordinary few weeks in New York City, as federal investigators have homed in on members of Adams' inner circle, producing a drum-beat of raids, subpoenas and high-level resignations that have thrust City Hall into crisis.

Federal prosecutors are believed to be leading multiple, separate inquiries involving Adams and his senior aides, relatives of those aides, campaign fundraising and possible influence peddling of the police and fire departments.

In the last two weeks alone, the city's police commissioner and head of the school's system have announced their resignations.

FBI agents 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.

In early September, federal investigators seized devices from his police commissioner, schools chancellor, two deputy mayors and other trusted confidants both in and out of City Hall.

All have denied wrongdoing.
