Acid Attack Being Investigated as Possible Hate Crime.
BALDWIN: Just in, the Trump administration just made one of the most -- President's most controversial decisions official. The State Department formally notifying the United Nations that the U.S. will withdraw from the Paris Climate Agreement. Keep in mind that agreement includes dozens of countries setting their own targets for reducing or controlling pollution. The deal was negotiated back in 2015. And now to this horrifying attack caught on security video in Milwaukee. You'll see the black and white video shows two men talking when suddenly one of them throws this liquid -- there you go, in the other's face, it turns out the liquid was acid. The victim, a U.S. citizen who was originally from Peru suffered second-degree burns, he tells police his attacker told him to go back to his country. CNN's Ryan Young is live on this one for us. Absolutely horrendous. I know police have arrested a suspect. He could face hate crimes. What more do you know?</s>RYAN YOUNG, CNN NATIONAL CORRESPONDENT: He could. Right now we've been told the man has been arrested but hasn't been officially charged. That is why we don't have his mug shot just yet, Brooke. And I've been asking questions all day not only to the police department but the DA's office there just to figure out exactly what the next steps are. We're told maybe Tuesday they'll figure out whether or not they charge him with a hate crime or other assault charges. But when you watch this video, it's so horrifying. This may have all started over a parking spot. And of course the two men decided to kind of go machismo with each other and have that argument right there. But then it takes that turn when the man starts pointing in his face. It looks like there might be a reaction but then you see whatever spilled toward his face. And when you see some of the video and see how the burned jacket this man is left with, you could see how much of his face probably hurt during this attack. In fact, listen to the victim talking about this attack and how he felt right after.</s>MAHUD VILLALAZ, ACID ATTACK VICTIM: I don't know that guy. I never saw him in my life. And he did that to me. Who carries a bottle of acid? My son called me today, daddy, what happened to you? What can I tell him? That some crazy guy did this to me.</s>YOUNG: Brooke, you could feel his pain. One of the things the victim also said, Mr. Mahud, he said, he said the man started screaming at him, you come to my country and try to evade it, you try to change my laws. Obviously, that was what was said apparently before that splash happened. Be interesting to see what happens tomorrow when the DA makes the decision in terms of charges, also to figure out has this man has had any run-ins before?</s>BALDWIN: Let us know what happens tomorrow, Ryan. Thank you very much. President Trump welcomed the World Series champs the Washington Nationals to the White House today. A handful of players from the team were absent from the celebration for unknown reasons. The catcher donned a MAGA hat and got an awkward hug from the President. The players also presented President Trump with a National's jersey and while the President praised the team for capturing the hearts of fans across the country, he couldn't pass up a chance to take a jab at the impeachment inquiry.</s>DONALD TRUMP, PRESIDENT OF THE UNITED STATES: Throughout this season, the Nationals captured the hearts of baseball fans across the region and across the country. America fell in love with the Nats baseball. They just fell in love with Nats baseball. That is all they wanted to talk about. That and impeachment. I like Nats baseball much more.</s>BALDWIN: This is the President's third public sporting event in the past ten days and got mixed reaction when he showed up for game five of the World Series. The President is now planning to attend the Alabama/LSU football game this weekend in Tuscaloosa. I'm Brooke Baldwin. Thank so much for being with me. Let's go to Washington. "THE LEAD" with Jake Tapper starts right now.</s>JAKE TAPPER, CNN HOST: The former U.S. Ambassador to Ukraine said she --
