House Judiciary Committee Chairman Jerrold Nadler (D-N.Y.) announced Saturday that the committee will immediately open an investigation into the Trump administration's decision to fire Manhattan U.S. attorney Geoff Berman.

"The House Judiciary Committee will immediately open an investigation into this incident, as part of our broader investigation into Barr’s unacceptable politicization of the Department of Justice," Nadler said in a statement.

"On Wednesday, the Committee will hear from two whistleblowers who will explain why Barr’s attempt to fire Mr. Berman is part of a larger, ongoing, and wholly unacceptable pattern of conduct. If the President removes Mr. Berman, then we will take additional steps to secure his testimony as well."
