The House Judiciary Committee is launching an investigation into President Trump’s firing this weekend of U.S. Attorney Geoffrey Berman, who has overseen prosecutions and probes of several associates of President Trump. On Friday night, Attorney General William Barr issued a press release claiming Berman was “stepping down” as head of the Southern District of New York, but then Berman announced he was not resigning and had no intention to resign. This led to a dramatic showdown that resulted in Barr sending Berman a letter on Saturday stating that President Trump had fired him. But then Trump distanced himself from the move, saying, “I’m not involved.” Barr initially tried to install his own pick to head the SDNY, but by Saturday it was announced that Berman’s deputy, Audrey Strauss, would temporarily take over.

As U.S. attorney, Berman had led the investigations of Trump’s former personal attorney Michael Cohen and Trump’s current attorney Rudy Giuliani. Berman also led the prosecution of the Turkish bank Halkbank, which had ties to Turkish President Recep Tayyip Erdogan.
