House Democrats want the FBI agents who have leaked information about the Hillary Clinton investigation to be found and punished, according to a letter sent to an independent investigator.

“These unauthorized and inaccurate leaks from within the FBI, particularly so close to a presidential election, are unprecedented,” Rep. Elijah Cummings, the top Democrat on the House Oversight and Government Reform Committee and top Judiciary Committee Democrat John Conyers wrote in a letter to the Justice Department’s inspector general. “For these reasons, we are calling on your office to conduct a thorough investigation to identify the sources of these and other leaks from the FBI and to recommend appropriate action.”
