Former White House official involved in 'unmasking' controversy joining Justice Department

A controversial former NSC official is joining the Department of Justice.

Trump has alleged that the department is slow-walking the request and has something to hide. Some Republican allies of the president have suggested a vote to hold top DOJ officials in contempt of Congress.

"We're not messing around here," Nunes said.

It's not clear what Cohen-Watnick's role will be at DOJ and there is no indication that it's directly related to the document production controversy. Cohen-Watnick did not immediately respond to requests for comment from ABC News.
