NORAH O’DONNELL: Nancy Cordes is our chief White House correspondent and Nancy, you covered this president closely. He's been criticized for sometimes flubbing a speech, going off script. Tonight was a bit different.
NANCY CORDES: Norah, this seemed to me to be a speech designed first and foremost to show that Joe Biden has the stamina and the fire in the belly to go another four years. It was designed to be delivered with high energy. He even broke into a call and response at one point and Democratic lawmakers played along. He told jokes. But he came out of the gate criticizing Donald Trump on Ukraine and then on January 6th. That was unexpected. He accused him of unleashing chaos when it comes to reproductive rights and pandering to Vladimir Putin. It seemed to me that this White House understood that one of the biggest obstacles to reelection for him are the persistent voter questions about the president's age. And the White House set out to try to address those questions with a speech in which he ad-libbed about everything from taxes to Snickers.
