President Donald Trump 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.

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

Trump’s attendance at the gathering in Washington for his first time as president is putting his administration’s often-contentious relationship with the press on full public display.

Trump was being watched closely at the event held by the organisation of reporters who cover him and his administration. Past presidents who have attended have generally spoken about the importance of free speech and the First Amendment, adding in some light roasts about individual journalists.

The Republican president did not attend during his first term or the first year of his second. He came as a guest in 2011, sitting in the audience as president Barack Obama, a Democrat, made some jokes about the New York real estate developer. Trump also attended as a private citizen in 2015.

Trump entered the subterranean banquet hall of the Washington Hilton to the strains of “Hail to the Chief” and greeted prominent journalists on the dais, also pausing to laud White House Press Secretary Karoline Leavitt with a cheerful pointing of his finger.
