The former defense lawyers for Michael Flynn at Covington & Burling on Monday defended their effort to transfer case files to the new attorneys representing the indicted former Trump national security adviser and denied clinging to client documents on the condition that an outstanding legal tab be paid.

Flynn terminated his Covington lawyers in June, hiring a new team of defense attorneys that include a conservative critic of Robert Mueller’s special counsel prosecutors. Earlier this month, Flynn’s new lawyers told Judge Emmet Sullivan of the U.S. District Court for the District of Columbia that the Covington team “has advised it will be several weeks before all of the information can be transferred.”
