In another post later, Trump said that "law enforcement has requested that we leave the premises, consistent with protocol, which we will do, immediately," noting that "The First Lady, plus the Vice-President, and all Cabinet members, are in perfect condition."

He added that the White House Correspondents' Dinner will be rescheduled within 30 days.

The US Secret Service said in a post on X that it is investigating "a shooting incident near the main magnetometer screening area" at the White House Correspondents' Dinner, in coordination with the Metropolitan Police Department.

"The president and the first lady are safe along (with) all protectees," the statement said. "One individual is in custody. The condition of those involved is not yet known, and law enforcement is actively assessing the situation."

Trump has been evacuated from the Dinner after the shooting at the Washington Hilton Hotel. Attendees were seen on the live broadcast ducking around their tables and taking cover.
