Good evening. We are breaking news in the attack of the White House correspondent's dinner.

New security of video. I want to show you, it's just been released. Take a look. On the top left of your screen, you'll see circled, the alleged attacker walk into a doorway with something that appears to be slung over his shoulder. He's actually followed by law enforcement officer with a canine. Then about 15 seconds goes by. Authorities are in the process of taking down one of the magnetometers

used to screen guests going to the dinner for weapons. From that same door, you're going to see the

alleged attacker suddenly emerge, running at full speed through the standing magnetometer right there,

fires at law enforcement. He goes out of frame, but clearly many of the officers now start to pursue

him, but I want to play it again slow down.

Here it is again. Now, I should note the slowing down in the video, the circles are all done by the U.S. Attorney for D.C.'s office who released this. We haven't done it.

Each circle represents a gunshot, they say. We know one Secret Service agent was shot once in the chest, survived because he was wearing a ballistic vest.

That same officer fired five times at the suspect.

You see those circles there.

And I just want to watch that play out.

This video of the suspect identified by authorities as Cole Allen on Friday night at the

hotel, Janine Piro, the U.S. Attorney for DC, released all of these videos on social media.

She says this shows Alan casing the area in the Hilton Hotel the day before the attack.

Also want to show you a video of him at the hotel gym.

He walks in there smiling, appearing to chat at some point with the hotel employee.

Then there's another video in a hallway.
