Ricky Waddell, the No. 2 official at the National Security Council (NSC), plans to leave his post, The Hill reports. It said the Army Reserve general was hired last May by Bolton’s predecessor, H.R. McMaster, to run operations at the NSC. He took over from K.T. McFarland, the deputy to Donald Trump’s first national security adviser, Michael Flynn. “Rick will be leaving and his departure date has yet to be confirmed,” according to a White House official. Waddell is the fourth top national security aide to leave or be ousted since new National Security Adviser John Bolton started in his role on Monday.
