Hundreds of former Justice Department officials signed onto a statement published Tuesday by the group Protect Democracy calling for Acting Attorney General Matt Whitaker to be replaced in that role by Deputy Attorney General Rod Rosenstein or another Senate-confirmed official.

“Mr. Whitaker has not been confirmed by the Senate, his qualifications to be the nation’s chief law enforcement officer have not been publicly reviewed, and he has not been fully vetted for any potential conflicts of interest,” the statement reads. “While we know that there are thousands of dedicated public servants now at the Department who will do their utmost to protect its mission and reputation, it falls to all of us to ensure that the Department’s role in maintaining the rule of law is not undermined or tainted.”
