Welcome to the lead. Im jake tapper. We begin with our national lead. What was supposed to be a fun night at a bar ending in tragedy and disaster. At least 12 people have been killed after a gunman opened fire at a California Bar last night. It was College Night with people dancing, playing pool, hanging out with friends. Police say the shooter was a 28yearold white man, and they add they had been called to his home before. Thats his home where he lived with his mother. They were called there because of a domestic disturbance. A neighbor telling cnn that the shooters mother lived in fear of her son. Authorities still do not know the motive behind the attack. Its a scene that has become all too common in the country. Its the worst mass shooting in 11 days, disturbingly cnn was told by at least one survivor of the shooting last night he was also a survivor of the shooting at las vegas at the route 91 Harvest Festival just over a year ago. More from outside the shooters house in newbury park, california. The shooter was known to Police Including this incident where apparently some Mental Health specialists were called to that home . Yeah. They came here. This is the second time this year that police had besendedde on this home. Police had known about this man, a troubled young man. The neighborhood knew and the mother spoke about her fears of her unstable son, the police, the neighborhood, the mother could still not have predict what had happened next. Weve got multiple people down. We need a lot of ambulances. Reporter initial 911 dispatches from the scene only hint at the horror unfolding inside. We have one victim. He was shot and is bleeding at the entrance. Reporter College Country night at borderline bar in Thousand Oaks, california, outside of los angeles had drawn a crowd of more than 100 young patrons. Parents now just beginning to learn which of their children will never return. Oh, son, i love you so much. Oh, heavenly, just please be with him. The gunman, ian david long was a 28yearold war veteran who entered the bar just before 11 30 p. M. Carrying a. 45 caliber glock and an extended magazine. I saw him point to the back of the cash register, and he just he just kept firing. He shot the front doorman, bouncer. Just a young man, and he shot the cashier. First responders rushed to the scene as survivors scrambled to escape. So they, unfortunately, are young people, people at night clubs, have learned that this may happen, and they they think about that. Reporter and then he broke through bar windows while others ran to hide in bathrooms and attics. Friends got the bar stools and they started slamming them against the windows so we could get out. Victims were carried out one by one and desperate lifesaving efforts took place in the parking lot. Still, many remained inside. Were still missing two people. We cant find them. The gunman was found dead inside the bars front office, an apparent suicide according to police. Were now learning he was a former marine, infantry machine gunner who served in afghanistan. He was also known to police. Last april Law Enforcement responded to a domestic disturbance at this newbury park home where he lived. Reporter the Mental Health experts out there cleared him that day. The deputies went out to the call with the crisis team that felt he might be suffering from ptsd. Richard berg who lives a block and a half away tells us longs mother feared for his future. Reporter she might have been afraid of him herself, i dont know. She never said that, but she was living in hell. Reporter the department of defense records show he was active marine for five years, from 2008 to 2013. It was after that that he enrolled at cal state northridge, but he did not graduate and that man that i spoke with, jake, richard berg, the neighbor who lives around the block. He says that his mother was often desperate. She would talk to neighbors lime hick how she wanted her son to get help at the v. A. But her son simply refused. Jake. Thanks so much. I want to bring in a Law Enforcement panel now. Ill start with you, phil mudd, the shooter was known to police for some minor incidents, but one in particular where Mental Health specialists were called. Take a listen to the sheriff. In april of this year, deputies were called to his house for a subject disturbing. They went to the house. They talked to him. He was somewhat irate and acting a little irrationally. They called out our crisis intervention team, our Mental Health specialist who met with him, talked to him and cleared him. So Law Enforcement knew about him. Mental Health Specialists went there. They ultimately cleared him. There are going to be people who say and ask did Law Enforcement drop the ball here. What do you think . Are you kid considering me. Wolf, pardon me. Jake. I live in an urban area. Im going to pass people with Mental Health disabilities when i go out to my home tonight. Instead of asking about this individual case, the question you have to ask is among the thousands of people encountered by Law Enforcement and psychological experts, 5,000, 10,000, 20000, how many pop out as exceptional . Is this person exceptional . When you get to that standard theres a couple other questions i would ask. One in particular would be what are your protections against legal action in the event you bring this person in and attempt to take their weapons . Put that in connection with Broward County where we also saw some Mental Health questions. If you see 10,000 of these, how certain can you be that you can pick out the one that can go ugly on it . Josh catch bell formerly of the fbi and now with cnn, police say, josh, they dont have any motive so far. What will they now be doing to try to figure out, no the that theres any reason that would make any sense, but to try to figure out why this happened so we heard earlier from authorities, jake, that they were waiting for a search warrant to go in to where the subject lived. That would potentially provide a treasure trove of information if they were able to go through a computer, if he left anything behind such a letter or manifesto or something that would allow them to get into the mindset of this person. We know he has as social media presence. Thats something they will be looking into no doubt and trying to get search warrants there, too. All thats going on. Right behind me is where they are doing the forensic examination, a very sad undertaking behind me because they are going through and processing the scene and trying to identify some of the victims and some of the bodies, so a multifacetted investigation here, jake, but ill tell you. We got here in the Early Morning hours covering this, and throughout the day it finally dawned on me, you know, that the American People are becoming experts in investigating mass murders. At some point they wont need us. They know by now what cops look for. They look at the motive and associates and the social media. Its really damning, an indictment of where were as a country that we continue to see these all over again and sad on a number of fronts, jake. And james galianos here with me. He apparently had one handgun. Is that unusual and does that tell you anything . Unusual from this sense, a handgun to do this type of damage, 12 killed here, but we need to recognize who this shooter was. Four and a half years in the corps, in the marine corps, not only that but served in afghanistan during some of our bloodiest fighting. 2009, 2010, 2011. He was there during the surge. He was also rated as a machine gunner. I mean, he carried an m240 or 249. He knew his way around weapons. If he had the extended mag that police talked about or was proficient in changing magazines, yeah, you could do that kind of damage if youre that skilled and a marine corps serviceman that served in the helmand proves where the bloodiest fighting for the corps was, yeah, he could accomplish that. Youre also a veteran, and youre not besmirching veterans. Youre saying he had a certain kind of skill that he learned. An aptitude, certainly. Some witnesses, phil, say the gunman used smoke bombs and they were unable to confirm that. If its true does that say anything about the planning or motivation . It doesnt say much to me. One of the simple questions i would have in that circumstance, jake, is to determine when the person acquired these. If they had them for years, that would suggest to me that those smoke bombs werent something that showed he was intending to conduct an action. If he acquired them in the past few days, your answer changes there. I think the issues here arent going to be about planning. They are going to be about the mental state of this person and what Mental Health professionals do when people in the neighborhood call in, again, as they did in that case in Broward County with the kid who shot up the high school. What do Law Enforcement and Mental Health professionals dozen . Today, thank you one and all for your expertise. Today a ceremony honoring the Ventura County sergeant who lost his life protecting everyone at the bar. Sergeant ron helus was a 29year year Law Enforcement veteran who was looking towards retirement in the next year or so. Moments ago we learned the name of another victim, alaina housley. She was the niece of tv actress Tamara Mowry Housley and also killed, cody coffman 22yearold with three younger brothers. Coffmans father had a heart wrenching press conference. A father burying his sone. Its almost impossible to watch. We are starting to learn more names of the dead now. These are young people whose lives had barely begun. We did just get the news that he was one of the 11 that were killed last night. Reporter jason coffman, father of 22yearold cody receives the worst news imaginable. His name was cody coffman. My first born son. Only him and i know how much i love how much i miss oh, god. This is so hard. Oh, son, i love you so much. Oh, heavenly father. Reporter for much. Day coffman hoped, prayed, his son was simply missing. He used the tracking function on his sons phone to find him. Its not moving. Its not moving. Thats the problem. The last thing coffman said to his son is dont drink and drive, and son, i love you. That was the last thing i said. Reporter shockingly others in the bar had survived the mass shooting in las vegas just last year. Unfortunately its the second time in about a year and a month that this has happened. I was at the las vegas route 91 mass shooting. Its a big thing for us. Were all a big family and, unfortunately, this family got hit twice in all, 13 are dead, including the gunman. At least 21 injured. When the call came, Sergeant Ron Helus was on the phone with his wife. Sergeant helus was having a conversation with his wife as he does several times during the shift and says, hey ive got to go. Handle a call. I love you. Ill talk to you later. Reporter as others rushed out, helus, a 29year veteran of the vent rah countys Sheriffs Office rushed in. When Sergeant Helus and the Highway Patrol officer went in, they immediately, changed gun mire with the suspect, and thats when the sergeant was shot several times. Helus who was planning for retirement was remembered today in a spur of the moment memorial. People lined the route as his body was moved from the hospital to the funeral home. Now also dead is 23yearold justin meek, his University Cal lutheran said he helped save lives before he was killed and alaina housley, the 22yearold you mentioned at the top, niece of adam housley who we know from the news business. He was a fox news reporter. We would see him out there, our best. All of our love goes to him and his family tonight. Jake. So awful. Miguel marquez, thanks so much.

Thats what a source close to the new acting attorney general Matthew Whitaker tells cnn despite the fact that hes been something of a frequent critic of special counsel Robert Muellers russia investigation, previously questioning the scope and reach of the investigation, calling muellers appointment ridiculous and fishy. Whitaker has even defended donald trump jr. s decision to seek dirt on Hillary Clinton from russians once it was offered, an act that even steve bannon he regard as treasonous. Whitaker spent some of his first day on the job at the side of the president and Deputy Attorney general Rod Rosenstein previously in charge of probe. Cnn jut tis correspondent Jessica Schneider joins us. Do you know if they could force him to recuse himself. Reporter this is a question for ethics advisers at the Justice Department, and really even if the advisers suggested that whitaker step aside, hes not obligated to follow their advice, especially since his questionable comments are more of a conflict of interest than a legal conflict, and tonight there are ample indications that whitaker has no plans to step aside. In his first full day as acting attorney general Matthew Whitaker went to the white house amid demands from democrats that he recuse himself from overseeing the russia probe, but whitaker has given no indication he believes he needs to recuse himself according to a source. That philosophy is echoed by white house officials who sources say also dont believe whitaker needs to step aside, and the Washington Post report that had people close to whitaker dont believe he would approve mueller seeking a subpoena for President Trump. My understanding of the scope is that it is limited. Reporter the news is no real surprise, since whitaker spent several months in 2017 making the rounds in the media, picking apart the special counsels case. There is no criminal obstruction of justice charge to be had here. The evidence is weak. Reporter whitaker was working as a legal commentator for cnn when he defended that trump tower meeting in june 2016 where donald trump jr. And others met with a russian lawyer who promised dirt on Hillary Clinton. To suggest that theres a conspiracy here. I mean, you would always take that meeting. Reporter on cnn. Com in august 20
