The U.S. Attorney’s office in Manhattan is perhaps the most prestigious federal prosecutor’s office in the country.
Mr. Berman worked there in the 1990s as a prosecutor, but took over the office in unusual circumstances.
Mr. Berman, a Republican who contributed to the President’s election campaign and worked in the same law firm as Mr. Giuliani, was never officially appointed to the post by President Trump or confirmed by the Senate.
In 2018, the then Attorney General of the United States, Jeff Sessions, appointed Mr. Berman as Acting U.S. Attorney in Manhattan.
But President Trump never officially sent Mr. Berman’s appointment to the Senate. After 120 days, his official appointment to the post was made by the judges of the United States district court.
American lawyers are generally replaced by their first assistants, but Mr. Berman is replaced by a foreigner who has never worked in this office.
It’s a very unusual move, but it’s not the first time this has happened under Trump. When Jessie K. Liu left the US attorney’s office in Washington, she was replaced by Mr. Barr’s ally, Timothy Shea, rather than her first assistant.
