#Walz: "He crossed a line ... #Trump over the weekend was talking about using the US Army against people who disagree with him. Just so you're clear about that -- that's you. That's what he's talking about. This is not some mythical thing out there. He called it 'the enemy within.' And to Donald Trump, anybody who doesn't agree with him is the enemy. I tell you that not to make you fearful or anything, I tell you that because we need to whip his butt and put this guy behind us."
