Secret Service agents protect President Trump after shots fired at the White House correspondents dinner Saturday night.

President Donald Trump was reported uninjured and other top leaders of the United States were evacuated from an annual dinner of White House correspondents on Saturday night after an unspecified threat. There did not immediately appear to be any injuries, and one law-enforcement official said a shooter opened fire.

The Secret Service and other authorities swarmed the banquet hall at the Washington Hilton as guests ducked under tables by the hundreds. “Out of the way, sir!” someone yelled. Others yelled to duck.

Most attendees are closed inside the ballroom and cannot leave

Dinner organizers said there will be an “announcement shortly, we will be resuming shortly” from the stage. Most attendees are closed inside the ballroom and can’t leave.

A block from the White House, party-goers headed to the Renwick Museum were instead gathered at police tape as the streets and sidewalks were blocked off. Police cars tore up and down the block, sirens blaring. A helicopter buzzed overhead.

Washington Hilton hotel commonly stays open to public, while security is focused on ballroom

Generally, the Hilton hotel, where the dinner has taken place for years, remains open to regular guests during the White House Correspondents’ Dinner, and security has typically been focused on the ballroom and rather than the hotel at large, with little screening for people not entering the dinner itself. In past years, that has created openings for disruptions in the lobby and other public spaces, including protests in which security moved to remove guests who unfurled banners or staged demonstrations.
