The White House has been put on lockdown after a man shot himself at the North Lawn.
The shooting happened at around noon on Saturday and sparked panic inside as staff were told to shelter in place.
The man’s condition is not known but DailyMail.com reports he was unconscious when police arrived at the scene.
It is not clear if he has been taken to hospital or if he is still at the site.
Political journalists sheltered in the briefing room and tweeted first about the breach.
Not long afterwards, the Secret Service said it was a person who had shot themselves.
The president is at Mar-a-Lago for the weekend with the First Lady and Barron.
DC police say it was a man who pulled a gun on himself. There is not thought to be any outstanding threat.
