MSNBC host Ari Melber asked former Watergate prosecutor Nick Ackerman on Thursday for his thoughts on former White House chief strategist Steve Bannon’s on-again and off-again decisions about testifying before Congress and the Mueller investigation.

Ackerman said that he believes Bannon’s claims of executive privilege are specious since he is claiming the protection for times before President Donald Trump was sworn in.

“There’s no such thing a ‘president-elect privilege,'” he said. “I’m extremely skeptical, here. To me, it all looks like a coverup.”
