Authorities said Cole Allen prepared a manifesto and shared posts to social media outlining his intent to target Trump administration officials ahead of the White House Correspondents' Dinner shooting.

President Donald Trump, first lady Melania Trump and other dignitaries are safe after a shooting incident outside the White House Correspondents' Association Dinner Saturday night at the Washington, D.

On March 31, 1981, when President Reagan was shot by John Hinckley, Jr., the Washington Hilton ceased to be just another venue for the Secret Service.

The sound of gunfire at the Washington Hilton Hotel carried echoes of President Ronald Reagan's shooting outside the same hotel more than four decades ago.

The US Secret Service confirmed that no one was injured in the "shooting incident", and one person has been taken into custody. In an address from the White House, the president said it was "always shocking when this happens, that never changes".
