 We have a special guest joining us now, the 46th president of the United States and presumptive Democratic nominee, Joe Biden, calling in to Morning Joe right now. Good morning, sir. Hey, Mika. I'm more of a presumptive. I'm going to be the Democratic nominee. Oh, I'm not the presumptive nominee. I'm going to be the nominee. And Mika was trying to jab him a little bit. Presumptive. We'll see what happens.
