DANA BASH, CNN ANCHOR: The mission to rescue 12 boys and their soccer coach trapped in a flooded Thai cave claimed the life of a former Thai Navy diver trying to rescue them. Let's get to Thailand and our Asia correspondent, David McKenzie, on the scene. David, what more do we know about that former Thai Navy SEAL, how he died?</s>DAVID MCKENZIE, CNN ASIA CORESPONDENT: Dana, it was a tragic death, of course, and trying to do the best he could to get oxygen to those boys stuck for more than two weeks in the cave. A few moments ago, a group of American military came in to help with this rescue effort. They are here. So are the Australians. Many international experts here to try and figure out how to get these boys out of that cave safely. The big issue now is that the oxygen is at times at critical levels. They have removed, according to a source, several of the Thai rescue teams who have been there comforting the boys, making sure their health is all right, out of the cave to help the oxygen levels. A source saying it's possibly unlikely, a Navy source from Thailand, that they will bring them out in the next 24 hours for fears of their safety. They're bringing in more kit to make sure the boys are safe if they decide to take them out that treacherous journey -- Dana?</s>BASH: Absolutely horrible. Thank you for the update. This is a hero trying to save these boys. Appreciate it. We will get back to you as we hear and learn more, David. Coming up, any moment now, Vice President Mike Pence is expected to speak at ICE headquarters in Washington. This, as a series of deadlines for families to be reunited starts today.
