House Minority Leader Kevin McCarthy, R-Calif., warned congressional Democrats against making any attempt to remove Attorney General William Barr from the Justice Department.

Barr appeared before the Senate Judiciary Committee on Wednesday, where he was grilled on his handling of special counsel Robert Mueller’s federal Russia investigation report. He was due to testify in front of the House Judiciary Committee on Thursday, but refused to be interviewed by staff lawyers for the panel as opposed to the lawmakers themselves, a format pushed by Chairman Jerrold Nadler, D-N.Y.
