 John Karl, thanks. I'm joined now by former Democrat and now independent Senator Joe Manchin of West Virginia, who still caucuses with the Democrats. Good morning, sir. Good morning, Martha. Good to be with you. And thank you for having me. You bet. You have known the president a very long time. He swore you into the Senate in 2010. So let me ask you directly, do you believe President Biden should step aside as the party's nominee?
