Cohen-Watnick, a protégé of ousted national security adviser Michael Flynn, was reportedly almost fired himself amid an internal struggle for control over national security policy in Trumps White House. Once Lt. Gen. H.R. McMaster replaced Flynn, he allegedly tried to fire the young intelligence official but was overruled after Chief White House Strategist Steve Bannon and senior adviser Jared Kushner, the presidents son-in-law, intervened.
Cohen-Watnick was later reported to be one of the sources who played a role in getting Nunes to the White House to view classified intelligence reports that Nunes claimed show the identities of members of Trumps campaign staff were inappropriately unmasked.
