From nbc news World Headquarters in new york, this is nbc nightly news with brian williams. Good evening. The initial news a few days back that a man had made it across the north lawn of the white house and inside the front door was bad enough, but we now know the intruder went well beyond the front door and deep into the white house itself, not far from the stairway and the elevator that take passengers up to the private family residence. The head of the secret service goes before a congressional hearing tomorrow. And she will again have a whole lot of explaining to do, while veterans of the secret service say its never been the same since it was pulled out of the Treasury Department and lumped in with Homeland Security after 9 11. This brings more unwelcome attention to the people who protect the president and the peoples house. Its where we begin tonight with nbcs kristen welker. Kristen, good evening. Reporter brian, good evening. When Omar Gonzalez forced his way into the white house earlier this month, even though the first family wasnt home, it was called an unprecedented security breach. The secret service initially said gonzalez was detained quickly after he entered the front door. Now as the Washington Post reported and nbc news confirmed, were learning gonzalez made it far inside the executive mansion. In fact, he ran past a staircase that leads to the first familys living quarters. Ten days after this fence jumper got on to the white house grounds, new details about security lapses that allowed him to get deep into the white house itself. Omar gonzalez jumped the fence around 7 20 p. M. , september 19th, ran across the north lawn, and burst into the front door which was unlocked. Secret Service Agents did not release dogs to chase him, nor fire weapons to stop him. According to a u. S. Official, gonzalez overpowered a female Uniformed Secret Service officer, unaware he had broken the first line of security because an alarm box had been muted at the request of the white house usher office. He barrelled past the guard, turned left and ran into the east room. He ran the entire length of the white house to the other end of the east room before he was tackled by a heavily armed counterassault agent near the doorway to the green room. This comes after another Washington Post report that when a man fired shots into the white house in 2011, it took the secret service four days to realize the residence had been hit seven times with bullets, and another day to arrest the man. Sasha was home at the time. The president and first lady were traveling and didnt learn about the incident for several days. They have been described, the president and she, of both fuming, because of think parents who think that their family is protected, but also by the way that the first lady learned this information. Reporter even before these latest revelations, a Congressional Committee was preparing to grill the director of the secret service, julia pierson. Shell be in the hot seat tomorrow. Im extremely concerned. Most organizations have acceptable losses. In other words, theyre right 97 of the time. In the case of the secret service, they have to succeed 100 of the time. Its clear that something needs to be done. And something needs to be done drastically. Its also clear they need to have a come to jesus moment. Reporter neither the white house nor the secret service are commenting on the latest reports and they defend their response to the 2011 incident, saying the shooter is serving 25 years in jail. Brian . Kristen welker on the north lawn in front of the residence for us tonight. Kristen, thanks. To another big story this evening, a new warning from the cdc about another mystery illness.

Hallie jackson, aurora, colorado for us tonight. Tonight, a paper trail is emerging of warnings about the growing threat of isis as far back as last winter. This comes as president obama made a notable admission on National Television which is now raising questions about how the red flags went unheeded by the Intelligence Community and the white house for so long. Our report tonight from our chief Foreign Affairs correspondent, andrea mitchell. Reporter the isis threat is not a secret, say intelligence leaders, to anyone watching or listening. Despite what the president told 60 minutes. Well, i think our head of the Intelligence Community, jim clappers acknowledged that i think they underestimated what had been taking place in syria.

Richard engel reports on nightly news. Reporter some Iraqi Security forces are fighting, but most appear to be stripping off their uniforms, leaving them in the streets and abandoning their posts, weapons and vehicles. Reporter now the pentagon acknowledges just how surprised it was by that. What surprised us certainly from a military perspective, was how quickly they moved into mosul over the summer. How fast that went. Their progress up north. As well as the way four or five iraqi divisions kind of melted away. Reporter so is this an intelligence failure or a failure of policymakers all the way up to the president of the United States . Those warnings were clear and loud. At least over the past two years in my view. Reporter bottom line, there are two issues here. The white house was repeatedly warned about the isis threat, but despite plenty of news reports, military and intelligence officials completely misjudged the iraqi armys ability to stand up and fight back.
