As Mueller Report Lands, Prosecutorial Focus Moves to New York

Mr. Khuzami’s departure will not directly affect most of the other Trump-related investigations, which Mr. Berman has supervised. Mr. Berman’s name, for example, appeared on a February grand jury subpoena served on the president’s inaugural committee.

For the most part, the investigations surrounding the president and his associates have been assigned to career prosecutors in the office’s public corruption unit, which has a track record of convicting politicians on both sides of the aisle. Those prosecutors work on the eighth floor of the building, down the hall from Mr. Berman’s office.

The unit is led by two office veterans, Russell Capone and Edward B. Diskant, and although line prosecutors shift in and out — one assistant who worked on the Cohen inquiry, Rachel Maimin, recently went into private practice, and another, Andrea M. Griswold, returned to work full time on securities cases — the unit has a deep bench.

Two prosecutors who worked on the Cohen case, Thomas McKay and Nicolas Roos, remain in the unit. The investigations are overseen by the office’s criminal division, which recently got a new chief, Laura G. Birger; she succeeded Lisa Zornberg, who left the office to return to private practice.

Robert B. Fiske Jr., a former United States attorney in Manhattan who later served as the first independent counsel investigating the Whitewater matter during the Clinton administration, said the Southern District prosecutors would maintain the kind of professionalism associated with Mr. Mueller’s team.

“If the question is, should the public have confidence that there will be the same kind of integrity and independence in the Southern District of New York that there has been in the Mueller investigation, the answer is absolutely,” Mr. Fiske said.
