President Trump has announced that White House counsel Don McGahn will be leaving his post in the coming weeks.
The pair's relationship has been strained amid reports that McGahn had been cooperating extensively with special counsel Robert Mueller's probe into alleged Russian election meddling.
McGahn's departure would mark the latest in a series of high-ranking advisers to leave the president's side.
As White House counsel, McGahn played a key role in Trump's efforts to revamp the federal judiciary with relatively young conservative justices.
Trump said McGahn is slated to leave after the confirmation of Supreme Court nominee Judge Brett Kavanaugh.
