NEW YORK (AP) — A former aide to New York City Mayor Eric Adams is discussing a possible deal with federal prosecutors following his arrest last month on charges of witness tampering and destruction of evidence, documents show judicial.

Mohamed Bahi, who served as the City Council’s top liaison to the Muslim community, was arrested last month as part of a wide-ranging investigation into Adams and his campaign fundraising that led to the mayor’s indictment on corruption charges in September.

In a court filing made public this week, prosecutors said discussions were underway with Bahi’s attorney. “regarding a possible disposition of this case.” The filing does not detail the nature of those discussions or whether a plea deal would require Bahi to cooperate with federal investigators.

Inquiries to the US Attorney’s Office in Manhattan were not answered. An attorney for Bahi, Derek Adams, also did not respond to a request for comment.

Adams pleaded not guilty to charges of accepting bribes to obtain free and discounted vacations abroad and illegal campaign contributions from foreign nationals, including a Turkish diplomat.

Bahi, 40, was charged two weeks later in another fundraising scheme. Prosecutors say he encouraged the owner of a Brooklyn construction company to reimburse four employees for their $2,000 donations to Adams, allowing the campaign to fraudulently obtain public matching funds.

An indictment said that after FBI agents contacted the construction company’s owner this summer, Bahi advised the businessman to lie to investigators, telling him that Adams believed he would not cooperate with authorities. When agents arrived to search Bahi’s own home in July, they say he deleted an encrypted messaging app from his cellphone that he had used to communicate with Adams.

Adams, a Democrat, denied ever telling a city employee to lie. And he has vowed to remain in office while fighting his own case. But the investigation has rocked City Hall in recent months, prompting resignations from the police commissioner, the schools chancellor and several top Adams aides.

On Friday, Adams’ longtime girlfriend, Tracey Collins, retired from her position as a senior adviser at the Department of Education. Prosecutors say he accompanied Adams on several foreign trips that were largely offset or discounted by a Turkish official seeking to take advantage of Adams’ influence.

At a hearing last month, Assistant U.S. Attorney Hagan Scotten said prosecutors are pursuing “several related investigations” and what is “likely” additional defendants will be charged and “possible” that more charges will be filed against Adams.

Adams’ trial is scheduled to begin in April.
