US President Donald Trump on Monday was abruptly pulled from a press briefing room as the White House went on lockdown.

Trump departed after a Secret Service agent appeared to speak to him at the podium. Another agent outside the room locked the doors, reported The Hill.

Trump returned a few minutes later, telling reporters he had been briefly pulled from the room because of a shooting outside the White House.

Fox News reporter John Roberts confirmed that he heard shots fired. Trump said the incident happened outside the White House grounds.
