New York City Mayor Eric Adams pleaded not guilty Friday to federal bribery charges, firmly rejecting allegations that he accepted luxury travel, campaign cash and other perks from foreign interests who then sought to harness his power and influence.

Adams' lawyer told a judge that they would move next week to dismiss the case, which has roiled the biggest U.S. city after months of investigations, searches and subpoenas.

Adams, a Democrat, entered the plea in a packed Manhattan courtroom that's just a short walk from City Hall, a day after prosecutors revealed an indictment alleging he accepted overseas travel and illegal campaign donations from people looking to buy his influence in city government.

“I am not guilty, your honor," Adams said, looking solemnly at Magistrate Judge Katharine Parker.

Adams left the courthouse without commenting. He smiled at a court officer but ignored the rows of reporters he passed on his way out. Afterward, Adams stood silently as his lawyer, Alex Spiro, railed against the charges.

“This isn’t even a real case. This is the airline upgrade corruption case,” Spiro said.

Adams is accused of exploiting a yearslong relationship with people tied to Turkey, who gave him free flights, hotel stays — even a trip to a Turkish bath —- and fueled his run for mayor with donations that helped him qualify for more than $10 million in public campaign funds.

People who aren’t U.S. citizens are banned by law from donating to U.S. political candidates.

He faces five counts in the indictment: wire fraud, bribery, two counts of receiving campaign contributions from a foreign national, and conspiracy. If convicted of the most serious charge, wire fraud, he faces up to 20 years in prison, federal prosecutors said.

Assistant U.S. Attorney Celia V. Cohen said prosecutors and Spiro came to an agreement that would allow Adams to be released “on his own signature,” with the condition that he not contact any witnesses or individuals in the indictment, with accommodations for him to speak with members of his family and staff — but not about anything pertaining to the allegations.

Prosecutors said they would provide Spiro with the names of people Adams must avoid.

Adams, 64, is due back in court Wednesday for a case conference.

Spiro told Parker, “We’ll be filing a motion to dismiss on Wednesday.”

Before the hearing, Adams gave a thumbs up but did not pause to speak to reporters as he headed into the courthouse flanked by his police security.

The indictment unsealed Thursday accused Adams of taking a variety of improper gifts from Turkish officials and businesspeople, including free hotel stays and deeply discounted airline tickets to destinations including France, China, Sri Lanka, India, Hungary, Ghana and Turkey.

In return, prosecutors said, Adams did favors for his patrons. That included helping Turkey get fire department approvals to open a new diplomatic tower in Manhattan, despite concerns about its fire safety system, prosecutors said.

Adams, a former police captain, says he is innocent. Spiro has said it was neither unusual nor improper for a government official to accept some travel perks. The mayor has denied ever knowingly accepting an illegal campaign contribution and said any help he gave people navigating city bureaucracy was just part of doing his job.

Shortly after the indictment was unsealed Thursday, Adams held a press conference at Gracie Mansion, where he said he did not plan to resign.

"We expected this. This is not surprising to us at all. The actions that have unfolded over the last 10 months, the leaks and commentary, the demonizing, this did not surprise us that we reached this day. And I ask New Yorkers to wait to hear our defense before making any judgments," he said.

Spiro told reporters that the travel perks and seat upgrades Adams accepted were commonly offered to VIPs and members of Congress.

“That’s what airlines do,” he said, noting that many of the charges relate to trips Adams took years ago when he was Brooklyn borough president.

Adams has so far weathered calls to resign from his critics, some Republicans and the field of potential Democratic primary challengers he is expected to face in next June’s mayoral primary. The New York Times editorial board, which did not endorse Adams when he was running for mayor in 2021, has also called on him to step down, arguing that he cannot continue to effectively govern the city while he fends off his criminal charges.

Notably, top Democrats such as Senate Majority Leader Chuck Schumer and House Democratic leader Hakeem Jeffries have not asked Adams to resign. Both issued statements after the indictment was unsealed saying the legal process should be allowed to play out. The New York Post’s editorial board similarly said Adams should be allowed to defend himself against the charges and described some what is alleged in the indictment as “small potatoes.”

Gov. Kathy Hochul, a Democrat who has the power to remove Adams from office, also did not call on Adams to resign, but she appeared to issue a warning to a mayor she has often sought to portray as a close ally.

“While I review my options and obligations as the governor of New York, I expect the mayor to take the next few days to review the situation and find an appropriate path forward to ensure the people of New York City are being well-served by their leaders,” Hochul said. “We must give New Yorkers confidence that there is steady, responsible leadership at every level of government.”

It is unclear whether Adams' indictment is the last word on federal investigations involving the administration.

Federal prosecutors are believed to be leading multiple, separate inquiries involving Adams and his senior aides and relatives of those aides. In early September, federal investigators seized devices from the police commissioner, schools chancellor, two deputy mayors and other trusted Adams confidants.

In the last two weeks alone, the police commissioner resigned and the schools chancellor announced he would retire. Neither has been charged with a crime or been publicly accused of wrongdoing.
