LEMON: Breaking news tonight in Miami. Search and rescue teams digging through the rubble of a collapsed pedestrian bridge, at least four people were killed. CNN National Correspondent Dianne Gallagher is there for us. Diane, hello to you. Fill us in on the latest. What are you learning?</s>DIANNE GALLAGHER, CNN NATIONAL CORRESPONDENT: So, Don, it is still a search and rescue mission. There are about 100 different crews going through the rubble of the bridge behind me here. They said they're going to work around the clock until they can make sure that they have found any survivors who still may be in there. They're using K-9, using radar, they want to make sure. And they said that it's not going to be a quick process, because these are very heavy pieces of concrete. And they have to be careful about how quickly to move things because if there are still survivors in there, the slightest move could cause some of these to collapse again. And they want to be as sure as they can at this point that if there is some survivor in there that they're able to save them.</s>LEMON: OK. They are just terrific. The NTSB is sending a team to investigate, Dianne, this collapse. What are you hearing just about how quickly this all happened?</s>GALLAGHER: Don, they are using words like earthquake, and that it looked like an explosion, it sounded like a bomb. They say it just happened in an instant. The bridge was there, and then it wasn't. It was flattened on the road. This wasn't a gradual fall. This was something that happened instantly. And that's what the NTSB, and state, and university officials are going to be looking at. What caused this $15 million, 950-ton bridge to fall like that.</s>LEMON: Dianne Gallagher in Miami. Dianne, thank you so much. I appreciate your reporting. When we come back, President Trump facing not one but two legal cases that are causing turmoil in his White House. My question is, how is the President getting anything done with a lawsuit by Stormy Daniels, and the Mueller investigation hanging over his head?
