Good morning and welcome to Morning Joe. We have a lot to cover on this Monday morning, May 23rd. The president continues his Asia trip. And the biggest headline from that trip so far came just a few hours ago when he said the U.S. military would get involved if China invaded Taiwan.

The White House was quick to clarify, and China was quick to respond.

We'll have those fast moving developments plus Ukraine's line in the sand when it comes to

negotiating a ceasefire.

We'll tell you what a top advisor to President Zelensky said and

developing news as you just heard on the formula crisis here at home baby formula

military planes carrying shipments from Europe arrived in the US yesterday will

tell you where it's headed and just how far it'll go in relieving the shortage. The answer, the short answer, not enough.

He's very excited. We're going to give him another chance. Don't know how he's going to, don't screw it up, okay? This is your last chance. Thank you for that. All right. And former age at the George W. Bush White House and State Department's Elise Jordan, MSNBC political analyst, and the host of way too early, Jonathan Lemire. He's White House Bureau Chief at Politico.

Also with us this morning, host an executive producer on the circus at Showtime, MSNBC National Affairs Analyst John Heilman. Good to have you all with us this morning. Let's get right into it.

President Biden today said that the U.S. military will get involved

militarily if China invades its island neighbor. This is how the president answered a
