In a Saturday appearance on MSNBC’s “AM Joy,” SiriusXM satellite radio’s Mark Thompson reacted to former Milwaukee County, WI Sheriff David Clarke saying “John who?” in response to being asked about Representative John Lewis (D-GA) and calling him “irrelevant.”

Thompson dismissed Clarke’s comments, calling him “crazy” and “an Uncle Tom.”

“We’ve all known [Clarke] to be crazy and he’s an Uncle Tom — we’ve all known that as well,” Thompson told host Joy Reid. “If it weren’t for John Lewis and the Civil Rights moment, he would never have been a sheriff and probably wouldn’t be on Fox News.”
