The ad’s narrator describes Rosenstein as “a weak careerist at the Justice Department protecting liberal Obama holdovers and the deep state instead of following the rule of law.”

“His incompetence and abuse of power have undermined congressional investigations, led to stonewalling and tarnished the credibility of the Department of Justice,” the narrator continues. “Time for him to stand up for the rule of law and stand up for the American people. It’s time for Rod Rosenstein to do his job, or resign.”

The controversial memo alleges that Rosenstein and other top Justice Department officials improperly used a piece of opposition research to obtain surveillance warrants against Trump campaign members. FBI officials strongly advised against publishing the memo, saying that it omits important context.
