At risk for flash flooding today, and texas is already under water. And this morning, the president s been on a bit of a retweet rampage, at one point retweeting more than 60 things in less than an hour. At the top of the president s mind now, the s p of donald trump jr. , warrant, and the mueller investigation. Joining us now, jeffrey diamond. Hes really on a tear when it comes to this naehring. He is. Retweeting in under 60 minutes. Thats what we saw from the president this morning as he got his day under way. As you mentioned, much of what the president was tweeting this morning is what has consumed much of his attention throughout this last week. One thing in particular that has unnerved the president is the subpoena by the Senate Intelligence committee over his son over the Mueller Report, the president retweeting multiple tweets about that issue and in particular echoing criticism from the chairman of that committee senator richard burr. We saw the president do what he has done so many times since the Mueller Report has come out. Thats on one side of things, using the conclusions o of the Mueller Report to claim vindication and at the same time attacking the investigators and the origins of that investigation. We saw that once again reflected in the president s twitter feed this morning. And just moments ago, another tweet from the president , this one from himself and about these tariffs that he has been focused on with regard to china. The president right now has left the white house as y. As you can tell behind me, the weather is fairly pleasant, 60 degrees or so. Perhaps a day for golfing. Thats usually what the president is up to when he leaves the white house on a saturday. All right. Jeremy diamond, thank you so much. We appreciate it. All right. Theres a lot to go over here. Joining me from california is california democrat representative judy chu, a member of the house ways and means committee. Good morning to you. Thank you very much for joining us. Thank you very much for having me. As you know, the chairman of your committee has issued a subpoena to basically try to get irs treasury to turn over tax documents not just his personal tax forms but i understand business as well. This is something, of course, you could ask for without a subpoena. So whats the reason for a subpoena . Well, a subpoena is one more tool in the toolbox, and it demands that those trump tax returns be turned over. The subpoenas been issued to the department of treasury cabinet secretary mnuchin as well as irs commissioner charles reddick, and it says that the tax returns must be turned over by friday. If not, then the House Counsel can request that we go to court and we can accelerate the Court Process even sooner, which may be a very good thing. It looks like you were headed to court anyway, right . That is right. There is a difference between answering the Court Process on a subpoena versus the tax code provision that allows us to get the return. Regardless, both cases are very legitimate, and, in fact, the law says that we shall get the return of the president or of any individual if so asked by the chair of ways and means. Yeah. Shall is one of those tricky legal words. Do you think the white house is going to turn ore the documents . Youre going to see the documents. Do you expect that before the time frame of the subpoena wears out . Remember, this is an attraction between the chair of the ways and means and the irs, so its not an issue of the president requesting it or saying that he wants to do it. Its between ways and means and the irs. Nonetheless, the pattern has been that they have not done it. However, we shall wait until friday. If they still dont do it, then we go to court. Why do you want to see the documents . What are you going to do with them . The president is the most powerful person in the United States. The president has the sole ability to sign federal laws into action, and he is also having exclusive ability over an entire branch of government. It is important for us to have accountability. But besides that, four decades of president s, both democrat and republican, have voluntarily turned over the tax returns to the American Public because they know that the American Public wants to see that our president s are complying with the law. Mmhmm. I want to ask you something before we run out of time here. Its something that we put to a republican we had on earlier. As you know, weve had another tragic shooting inside of a school. This year, weve had so many heartbreaking episodes of this to the point where children are now having to fight back, and im wondering what are democrats doing to focus on the issue of resolving this, whether its background checks, whether its gun control, whether its Mental Health . What is being done to prevent this from happening again next week . Well, you know that we have been working very hard on this, and, in fact, one of the first things we did was to pass a bill that did, amongst other things, a universal background check that could actually encompass everybody, that could make sure that those that were selling guns at gun shows or online or in person also had to comply with a background check. That is the most effective way of making sure that people who have these guns but shouldnt have them indeed dont have them. And why hasnt it happened . The senate has refused to take up this bill. We believe that there should be pressure on the senate to take up this bill so that there can be finally commonsense gun reform in this country. Representative judy chu. Thank you very much for coming in and talking to us today. Its a pleasure to see you. Thank you so much. Well, its an aboutface for rudy giuliani. Hours after he said he was going to go to the ukraine to push questions about joe biden, now he says hes not going to do. Ill get out of it in order to rule out any political suggestion, ill step back and watch it unfold. Rudy giuliani originally said he wanted to make that call but his opponents went to the fact that the prosecutor had been investigating a Ukrainian Natural Gas Company that was connected to bidens son. The investigation was later dropped after the prosecutor was removed. Breaking news this hour. Three gunmen have stormed a fivestar hotel, and there are reports of gunfire inside the building. This is all taking place in pakistan. And joining us right now is ben farmer. He is in islamabad, pakistan. And, ben, what are you hearing about this attack . Reporter well, we understand that its three gunmen who have attacked the hotel in the port city. Its in southern pakistan. On the arabian sea, and its a strategically important port for pakistan. We understand there is gunfire. There are some reports of blasts, although, these are not confirmed, and it seems the gunmen did enter the hotel. We dont know who they are, and theres been no claim of responsibility. The latest we have from the authorities is that they have evacuated guests from the hotel, but its not clear if all the staff are evacuated yet. And, ben, do we know who usually frequents this hotel . In other words, what kind of clientele they would have . Would there be foreigners there . Reporter yes, there would likely be foreign nevers there. Its the focal point of an enormous amount of Chinese Investment at the moment, so there will be a lot of chinese businesspeople there. There may also be tourists there. Its really a very, very important port city for pakistan. As you say, no one has taken responsibility here, and we dont know if this is a straight out terror attack, in other words, to kill as many as possible, oer whether its a hostage situation. Reporter no, we dont know what the motivation is of this attack and we dont know who is conducting it. Gwadar is in the province that has seen a lot of insurgency. There are separatist insurgents who have in the past attacked both government and chinese targets. But as you say, we dont know whos responsible. And was there any indication this might have been coming . Have there been problems or any threats . Reporter we dont know about particular threats to this particular target, but, yes, there have been attacks on government targets on chinese targets and, indeed, elsewhere in the country in recent months. All right. Well, ben farmer, well continue to stay in touch with you to keep on top of the circumstances there. Thank you very much for that update. Well, the gulf coast is under a Flash Flood Watch. Rain and thunderstorms are threatening to hit that area again, and theres already a lot of water there. Were going to tell you what to expect. Right now the coast guard is dealing with an environmental hazard after a taker collide with a barge in the middle of the Houston Ship Channel. And possible warning signs in the weeks and months before the Colorado School shooting. We hear from one of the classmates who says one of the suspects joked about killing his classmates. Else.

Severe thunderstorms and torrential rain have been pounding texas, louisiana, and mississippi. 20 Million People are under a Flash Flood Watch today. Look at what it looks like in parts of houston. And theres more rain expected to cause even more flooding there. Ads you can see, those cars and trucks barely making it through. Cnns ed lavandera is live in houston. Ed, i know the rains have let up a little bit, but there could be more rains eventually coming at you, right . Reporter yeah, they are expecting a little bit more rain this afternoon here in the coming hours. That would be the third round of wave that has hit this area this week. You know, houston is the city that floods. Its a city thats used to this. Watching the floodwaters rise from the bayous and tributary systems that cut through much of the houston area, so some concern about how much rain will fall here this afternoon and what exactly it will mean in terms of flooding. The good news has been that we havent seen any rain here in the last 24 hours, and that has allowed the floodwaters to recede substantially, which will make it a lot easier for this area to absorb the rainfall thats expected here in the next couple of hours. So that is some good news. Also, emergency officials here are dealing with another crisis. A barge was almost cut in half in the Houston Ship Channel, dumping 25,000 gallons of whats been described as gasoline stock product there into the Houston Ship Channel. Emergency crews have launched a 1,600 feet of boon to contain it as much as they can. Theyve been urging people up and down the coastline to stay away. Theres aroundtheclock air monitoring testing thats going on, weve been told. As far as we know, no severe impact to residents in that area. The air monitoring testing, were told, has come back in the negative and everything is okay, but that will continue. Its rather striking images coming from that Houston Ship Channel where two vessels collided and one of those barges almost sliced in half. Were looking at the images now. One quick question. Houston suffered horribly under Hurricane Harvey with the flooding they had. Is the flooding occurring in some of those same neighborhoods, or is this a different area . Reporter its very widespread, so its really hard to grasp. There are some areas prone to flooding. People know where those areas are. Also it just depends where the most intensive rainfall drops. So flooding can pop up in other locations. Its very quick. These are flash flooding areas. Some areas are prone to flooding and it doesnt take much for areas to rise up, but in other areas, they pop up in various different places . Okay. Got it. Ed lavandera, thank you so much. One of the Colorado School shooting suspects, quote, always joked about killing his classmates. That is at least according to a former student at the stem School Highlands ranch. Remember two suspects were arrested this week after police say they killed one student and injured eight others at the school. Scott mclean is with us from highlands ranch, colorado. Scott, i know some people are even talking more about this today. Talk to us about what weve learned about what one of these suspects was saying before, you know, sometimes months before this happened. Reporter yeah. Years before really, christi and martin. A lot of people are wondering how this could happen here including this former stem student kevin cole who said he was stunned to hear about the shooting but not surprised then to hear one of the suspects was his old friend 18yearold devon erickson. He liked to get a rise out of people and he was shorttempered especially when it came to his political views. More concerning were his offcolor jokes or threats he had made. One, for instance, he would whisper to cole on several occasions, dont come to school tomorrow. He also said things like this. Listen. He would walk into the classroom and from time to time he would say just like we always thought it was a joke. He would say when the pencil hits the floor im going to start shooting, and he would drop pencils randomly and students would hear this and go home and tell their parents and they would tell higher faculty about events that could conspire. So cole says at the time these things were sort of laughed off as a joke, but now they seem more like warning signs that were missed. He said that erickson had actually harassed and bullied his brother during the years he was at stem and thats what eventually soured their friendship. Martin and christi. Scott, there was apparently a parent who came forward anonymously that somehow the highpressure learning environment was going to lead to another kind of columbine, and im wondering what are people saying about that. Reporter yes. So this parent described a sort of pressure cookertype environment. She actually said, yeah, she was worried this could escalate toward someone getting hurt or even killed. The school says there simply is no basis for the allegations and they fielded a Defamation Case against this anonymous parent. We spoke yesterday and they said, yes, the school demands excellence of its zool, but its also an Inclusive School and a place where students are free to learn by trying things and failing. Listen. Its kind of frustrating to hear people characterize it as a super High Pressure kind of place. The pressure kids feel at stem is either pressure that we parents are putting on them directly or that theyre putting on themselves. Its not the school that is really pressuring them that i have found. Reporter so as for security at the school, on the day of the shooting, there was no School Resource officer there, and the county Sheriffs Office explained yesterday why that was, saying that the year before there was a dispute between the Sheriffs Office and the school itself on cost and the responsibility of that School Resource officer and the contract was not renewed, so instead the school hired a private security guard, and according to the private Security Company that hired that guard, he was involved in apprehending one of those suspects. Martin and christi. Interesting. All right. Scott mclean, thanks very much. Good to hear from you. Well, were told be prepared for sticker shock.
