Calls are mounting for MSNBC host Chris Matthews to resign following his remarks comparing Senator Sanders’s Nevada victory to Nazi Germany’s takeover of France.

Chris Matthews: “I’m reading last night about the fall of France in the summer of 1940. And the general, Reynaud, calls up Churchill and says, ’It’s over.’ And Churchill says, 'How can it be? You've got the greatest army in Europe. How can it be over?’ He said, ’It’s over.’ So I had that suppressed feeling. I can’t be as wild as Carvill, but he is damn smart, and I think he’s damn right on this one.”

Bernie Sanders’s communications director, Mike Casca, responded to Matthews’s comment on Twitter, saying, “never thought part of my job would be pleading with a national news network to stop likening the campaign of a jewish presidential candidate whose family was wiped out by the nazis to the third reich. but here we are.”
