The newly confirmed Justice Department official who authored the memo condemning fired FBI Director Jim Comey has been “compromised” by President Trump, according to a senior House Democrat.

Rep. Eliot Engel, D-N.Y., accused deputy Attorney General Rod Rosenstein of displaying “a remarkable lack of integrity” by authoring a memo that argued for firing Comey in light of his violation of DOJ rules during the Clinton email investigation. Rosenstein, in concert with Attorney General Jeff Sessions, issued a formal recommendation that Comey be fired earlier this week, which Trump implemented immediately.
