Now, Justice Department officials have said that Alan will face charges.

As of now, the initial ones are expected to be

assault on a federal officer with a dangerous weapon and using a firearm in a crime of violence.

They also expect to add more down the line.

NPR's Ryan Lucas has more.

Shots were fired Saturday night at the Hilton Hotel where President Trump and other administration officials were attending the White House Correspondents' Dinner.

Authorities say the suspect, Cole Allen, had tried to rush past security and stormed the ballroom where the event was taking place.

Officials say Allen was armed with guns and knives.

Investigators have been scrambling to collect evidence since the incident.

Acting Attorney General Todd Blanch says preliminary information indicates the suspect was targeting members of the Trump administration.

Ryan Lucas, NPR News, Washington.

Look, this incident happened late Saturday night, so it is still very early in this investigation.

But law enforcement here in Washington, D.C.

and in Southern California have been hard at work trying to collect evidence, put the pieces together.

Much of what we know at this point comes from Acting Attorney General Todd Blanch, who made the rounds on the Sunday talk shows.

Blanche didn't identify the suspect, but as you said, NPR has confirmed the individual in custody is 31-year-old Cole Allen from Torrance, California.

Now, Allen has not been cooperating with investigators.

That's according to Blanche.

But Blanche says authorities have been interviewing witnesses, people who know the suspect, and investigators also have executed search warrants at locations associated with them, and they've done the same thing on his electronic devices.

And have they found anything so far?
