MSNBC's Andrea Mitchell: "I've never seen anything like it. The chair of the Democratic Party, a Congresswoman from Florida, who has bee enormously popular in her district... was absolutely booed by protesting Bernie Sanders supporters, right off of the stage. She had to break off her speech, finally gave up and was escorted out by security. I've never seen anything like it."
"And it is only a hint of what would happen if she shows up on the podium [on the convention floor]."
"I can't see how she could show up on that podum without amplifying what just happened."
