Morning Joe kicked off with the panel recapping the last night of the Democratic National Convention, during which the father of a Muslim soldier who lost his life fighting for the United States addressed the crowd and Republican presidential nominee Donald Trump directly. “When Mr. Khan looked into the camera and said to that convention crowd and to the United States of America about Donald Trump: ‘You have sacrificed nothing and no one,’ I began to cry,” said veteran columnist Mike Barnicle. “I don’t know if there’s anything you can do if you’re Donald Trump. You can’t tweet this one away.” Hear the rest of the conversation with Mika Brzezinski and Joe Scarborough here. Only on MSNBC live from Philadelphia.
