MSNBC contributor Claire McCaskill said Tuesday on “Deadline” that she found it “incredibly depressing” that so many Americans have been “fooled” by former President Donald Trump. Discussing President Joe Biden’s campaign, McCaskill said, “I think he’s trying to do what Liz Cheney did with the January 6 Committee, and that is to escape the drip, drip, drip of depressing facts about what has happened in America and elevate the conversation to something much bigger, much broader, much more important, and that’s our values.”
