New surveillance camera footage has been released showing the White House Correspondents' Dinner gunman charging through security.
New surveillance camera footage has been released showing the White House Correspondents' Dinner gunman charging through security.
The footage, released by the US Attorney's Office in the District of Columbia, shows Cole Allen barge through the security checkpoint at the Washington Hilton Hotel.
With most of the guests already in the ballroom, officers are midway through packing up one of the metal detectors at the time of the major breach.

The video shows Allen running past a group of officers while he holds a shotgun.
It shows one police officer firing their gun three times at point-blank range as Allen runs past.
Other agents are standing behind Allen when the officer fires unsuccessfully at him, but it does not appear any of them are struck.
The footage is released as the government is facing questions as to how a Secret Service agent was injured in the shooting.
The agent was taken to hospital after being apparently struck with a bullet while wearing a bullet-proof vest.
"There is no evidence the shooting was the result of friendly fire," US Attorney Jeanine Pirro said.
"My office along with the FBI will continue this extensive investigation to bring Cole Allen to justice."

Allen's lawyers have questioned whether their client actually fired his shotgun during the security breach.
They told a Washington court that there is no visible muzzle flash coming from Allen's gun.
Prosecutors told the court they had found what appeared to be a buckshot pellet at the scene.
Such a pellet would indicate Allen did fire his shotgun.
A typical 12-gauge shotgun shell will contain about nine pellets, which resemble ball bearings.
But Allen has not been charged with shooting the officer, but still faces life behind bars on other charges.

Speaking today, President Donald Trump backed Pirro, a former Fox News host appointed to the high-profile position by him.
"They said it wasn't friendly fire, it wasn't us," Trump said.
He brushed off suggestions he start wearing a bulletproof vest.
"I don't know if I can handle being 20 pounds heavier," he said.
Other footage released this morning shows Allen walking down a hallway at the hotel and looking around the gym.
Pirro said the video indicated Allen was "casing the area" the day before the breach.
Allen did not seek to be released on bail while appearing in court today.
