President Trump evacuated after security incident at White House correspondents dinner

President Donald Trump and other top officials were evacuated from the annual White House Correspondents Dinner after security incident.

Secret Service agents swarmed the ballroom at the Washington Hilton Hotel, where some reporters, administration officials and dignitaries ducked under their tables amid the confusion.

It was not immediately clear what prompted security to stop the event and usher Trump out of the room. Other attendees remain in the ballroom.

Some attendees reported several loud bangs, but were unable to place them or identify the source.

NBC News reached out to D.C. police, the Secret Service and the Justice Department for more information.

Saturday marked Trump’s first time attending the dinner as president. Trump had been the only president in the event’s centurylong history not to attend at least once while in office. In years past, presidents have typically endured a light roasting from the dinner’s headliner, typically a comedian.
