 ABC News, I'm Brian Clark. President Biden campaigning this morning in Philadelphia, attending a church event at the start of what ABC political director Rick Klein calls a very consequential week. He's got the NATO summit here in Washington, a press conference on Thursday. This is an absolutely critical time for him to prove to these Democrats that he can keep their confidence. When he said that none of them have asked for him to step aside in the leadership, he is testing that proposition in the next couple of days.
