A big accusation lobbed by the mayor's defense attorney: federal prosecutors, they say, have been leaking secret grand jury information to the media for months.

The accusation was on full display this week at a press conference by the mayor's attorney, and then in court papers filed Tuesday.

In them, the mayor's attorney accuses federal prosecutors of leaking material to "aggrandize itself, further its investigation, and unfairly prejudice the defendant, Mayor Eric Adams."

Grand jury proceedings are conducted in secret to protect witnesses and the accused.

Still the mayor's court papers go through a litany of headlines - proof, they argue, that federal prosecutors were leaking to the media.

Going further, they are requesting an evidentiary hearing to divulge the "prosecution team's misconduct" and determine an appropriate remedy. Not surprisingly, they suggest the judge should dismiss the case.

“We have a system of justice where we try cases in courtrooms and not in boardrooms or the streets,” the mayor said Tuesday. “And I spoke with my counsel over and over again and stated to them, you know, this is just not right.”

The mayor will be back in court on Wednesday. It's unclear if the judge will make an immediate determination regarding this request.

The U.S. attorney's office for the southern district, which is trying the case, declined comment.
