Yeah, as we all saw in that haunting video posted by President Trump, 31-year-old Cole Allen sprinted through a security checkpoint at the Correspondents' Dinner armed with a shotgun, handgun, and multiple knives.

Now, from what we know, he fired at least one shot, striking a Secret Service officer in their bulletproof vest.

Thankfully, that officer was released from the hospital Sunday morning.

And after a brief exchange of gunfire, he was then tackled by a number of other agents.

Police say that Allen had earlier in the week booked a room in the Hilton Hotel.

That's where the event was taking place.

And ironically, the same hotel where President Reagan was shot back in 1981.

Allen was taken to a local hospital after the shooting with minor injuries before being transferred to a D.C.

detention facility on Sunday.

He'll have his first court appearance later today, where he will be charged with at least two counts, including use of a firearm during a violent crime and assault on federal officers.

However, according to DOJ officials, he is likely to face more serious charges as the investigation proceeds.

There could be something related to terrorism or hate crime charges as well.

Well, according to authorities, the California native had a deep hatred of President Trump and really his entire administration.

Just before opening fire, Cole reportedly sent his family a manifesto referring to himself as the, quote, friendly federal assassin.

At least some members of his immediate family were concerned and contacted law enforcement.

but by then it was too late.

The New York Post has since obtained that manifesto and as expected, it is full of anti-Trump rhetoric.

He starts by apologizing to his family before making clear that he had compiled a specific list with rankings of White House officials that he planned to kill while saying, quote, I experienced rage thinking about everything this administration has done.

And to that point, Cole includes a number of references to Trump era policies and actions, including ICE detention facilities, civilian casualties of war in Iran,

And even drug smugglers who had been killed, he refers to them as fishermen, by the Navy off the coast of South America.
