 It's a very big deal that NATO is meeting here in D.C. this week at a critical time for Europe as Russia continues to try to take over parts of Ukraine. The pressure on any U.S. president hosting the NATO event would be immense. And in the case of Joe Biden, he is having to navigate the summit at a time when an increasing number of Democratic lawmakers are calling for him to leave the presidential race. Joining us live, Michael O'Hanlon, senior fellow and director of research in foreign policy at the Brookings Institution. Michael, it's always good to talk to you. Thanks so much for joining us this afternoon.
