New York City Mayor Eric Adams may soon face additional charges in his federal corruption case, with prosecutors indicating on Wednesday that further counts are “quite likely” and that more defendants may be implicated.

Prosecutors with the U.S. Attorney’s Office for the Southern District of New York shared the developments during a hearing in a Manhattan courtroom before U.S. District Judge Dale Ho, marking Adams’s second appearance in court since he pleaded not guilty to corruption charges last week. More counts against the mayor are “possible,” said prosecutors, who also indicated the case would include “multiple witnesses” against the mayor.
