 This is not the conversation that they want to be having in this moment. They have insisted a lot that this is going to be an election that they want to see as a contrast election. They don't want to see this 2024 campaign as a referendum. And when Biden missteps, it recreates and refocuses the attention on him and some of the concerns that voters have about his age. That's NPR White House correspondent Asma Khalid in the room for President Biden's press conference later this evening. Thanks, Asma.
