The position is reportedly involved in the Trump-Russia investigation.
Attorney General Jeff Sessions on Wednesday named Geoffrey Berman to succeed Preet Bharara as U.S. attorney for the Southern District of New York on an interim basis, 10 months after Trump fired Bharara in a purge of all federal prosecutors. The U.S. attorney in Manhattan is crucial because the district is home to Trump Tower, where a meeting between Trump campaign officials and Kremlin-linked Russians occurred in 2016.
...The Wall Street Journal reported in October that the Southern District of New York was working with Special Counsel Robert Mueller to investigate Paul Manafort, Trump’s 2016 campaign chairman, for alleged money laundering. Days later, Mueller’s team announced charges against Manafort. He has pleaded not guilty.
According to Sessions' testimony before the Senate in October, Trump involved himself in the interviewing process of potential U.S. attorneys, which legal experts indicated is both unusual and inappropriate.
