Megan is live to tell us what happened. Reporter barbara, you can see behind me here the suspects suv and there are quite a few bullet holes. I counted at least seven and we have shattered windows as well.

D. C. Police responding to shots fired found themselves under fire overnight. It happened behind Martin Luther king junior elementary on alabama i saw it and the police saying get out, get down. Reporter a police spotter which picks up gun shots in the area sent out an alert. When Police Arrived they saw several people in an suv and thats when the shots rang out opening fire on the officers with Police Firing back. You could tell it was a battle of gun fire because it was more than one gun and it was consistent for a few minutes. Reporter no one was hurt but the suspects initially refused to get out the suv. They then sur rended about 30 minutes later without incident. All the suspects were taken into custody but it appears that only one has been arrested. The others however are being interviewed.

The beginning of metros fourth safe track surge caused delays this morning at Reagan International airport. This time the blue and yellow lines are closed from Reagan International north to pentagon city. You should hop on at another location. Those shuttles run every five minutes. Passengers we spoke with say theyre just trying to roll with the changes. Instead of stopping here were going to get off at pentagon so its not much of an inconvenience. Im no longer riding but i think theyve done a good job handling it so far. This fourth surge will last until next monday and then the next shut down will be in october. A major story developing right people are dead after two trains collided head on in italy. Were getting this video from the scene. Theres a lot of carnage there. The trains belong to a private company and those cars are crushed and destroyed. There are survivors, including a small child. This is going to involve a long investigation before we find out what happened. Today d. C. Mayor will introduce to help Police Recruit more officers.

Sanders is expected to endorse his former opponent. Well look at how this could change the president ial race. The attorney gen woman i have a masurprise for you. Are you . Man you have a surprise for me . Narrator at dominion, 1 in 5 new hires is a veteran. And when theyre away, they miss out on a lot. But they wont miss out on financial support. Because we cover any difference between their military pay and their dominion salary, and continue benefits for them and their families. Why do we do it . Because our vets sacrifice enough. Dominion. Depend on us for more than energy. Stand by me. Were still waiting afor th appearance of Hillary Clinton and Bernie Sanders is expected to endorse her. Sanders is finally expected to endorse Hillary Clinton at this rally taking place. Were joined by mark murray. Talk about Hillary Clinton had to do to get this endorsement and how much it will help her. Part of it was wowing Bernie Sanders. They had a meeting in Hillary Clintons home and president Obama Meeting with Bernie Sanders and maybe the most important part of this was the democratic platform going on last weekend and Bernie Sanders getting big victories when it comes to the minimum wage and health care and trade and something that he can say to his supporters we were what will people be watching for at this event. What im going to be watching for is how genuine the endorsement is. Sometimes you say i back somebody but it doesnt seem like someone really means it or not and everybody is going to be looking to see how sincere that is. Its important for Hillary Clinton, our poll found 78 of supporters said they would vote for Hillary Clinton over donald trump. Thats good but that number could be boosted up. If that happens you would see Hillary Clintons numbers go up against donald trump a point or two and thats significant. Sanders hasnt abandoned his own campaign and isnt expected do that until the convention. Thats right. Hes not going to be suspending his campaign. Part of his message has been the revolution continues and sometimes its hard to extinguish a revolution if you extinguish your campaign. But the lead has shrunk. Is part of that due to the email. Hillary clintons went down one percentage point and Donald Trumps up one percentage point. Theres political noise. Theres no doubt compared to last week its a closer race but its important to note the overall trends and almost every poll has Hillary Clinton ahead. Do you think the trouble in the country right now with the Police Shootings in dallas and all the other shootings are having any impact yet. We havent been able to see any impact. Its a story we have to watch for and see about president obamas reaction when hes in dallas today, the memorial for those Police Officers. But this is a case of any president ial election all these external factors sometimes matter and sometimes they dont and we have to keep muwatching. Well have more on the rally at right now the attorney general is testifying before the house committee. This is her first time on capitol hill since she announced Hillary Clinton would not be prosecuted over her emails. The American People expect government officials to abide by the law just like everyone else. To be reprimanded when they break the law. That is not the case for former secretary of state Hillary Clinton. While i understand that this investigation has generated significant public interest, as attorney general it would be inappropriate for me to comment further on the underlying facts of the investigation or the legal basis for the teams recommendation. The hearing started with a moment of silence for the five Police Officers killed in dallas. Now to a developing story in michigan. The county sheriff says larry shot and killed deputies yesterday. Thats different from what was said last night. He said he got the wrong information when he was gordan was not restrained. Several people shot while attending a vigil for a victim of gun violence.

The county activated the 311 call center to help answer emergency questions. A study found that medical errors cause up to 250,000 deaths every year, making those mistakes the third leading cause of death in this country.

These are the collective causes that comprise the problem of people dying when they should not, people dying underour care. Reporter the doctor underscores that most of the mistakes are not due to bad doctors. We shouldnt look to doctors to blame the problem on individuals.
