President Donald Trump's outside counsel will file a leak complaint regarding former FBI Director James Comey's leaked memos with the Department of Justice, a source close to the outside legal team tells NBC News.

Trump lawyer Marc Kasowitz will file the complaint with the DOJ's Inspector General and the Senate Judiciary Committee after Comey testified Thursday that he allowed a personal friend to leak unclassified memos of his conversations with the president to news outlets in hopes it would trigger the appointment of a special counsel.

"I asked a friend of mine to share the content of a memo with the reporter," Comey told the Senate yesterday during several hours of questioning. "I didn't do it myself for a variety of reasons, but I asked him to because I thought that might prompt the appointment of a special counsel."
