The former chief spokesperson for the Department of Justice said "every senior official" at DOJ has an obligation to resign if Acting Attorney General Matt Whitaker does not recuse himself from special counsel Robert Mueller's investigation.

Matt Miller served as director of the office of public affairs for the Justice Department and joined MSNBC's "Deadline: White House" with Nicolle Wallace on Wednesday.

"I think anyone that cares about the rule of law in this country -- whether they are Republican, Democratic, or independent -- now is the time to make your voices heard," Miller suggested.

"You used to advise the Attorney General," host Nicolle Wallace noted. "How would you advise the Deputy Attorney General, right now, today. What should Rod Rosenstein do?"

Miller said he would suggest Rosenstein wait to see if Whitaker would recuse himself.

"But if it's clear he's just there to shut this down, I think Rod Rosenstein and every senior official have an obligation to step down and make it exactly clear the Department of Justice is being abused and is being taken over by the White House and it cannot stand," he concluded.
