The White House has been put on lockdown after a vehicle struck a security barrier.
Donald Trump was in the building at the time a female driver was apprehended, with the US President hosting Australian Prime Minister Malcolm Turnbull on Friday.
A white Chevrolet with a smashed window was pictured near a security barrier.
It was reported a woman had been pulled out of the vehicle's window at gunpoint.
The US Secret Service said on Twitter: "An individual driving a passenger vehicle struck a security barrier near the White House at 17th & E.
"The vehicle did not breach the security barrier of the White House complex.
"The female driver of the vehicle was immediately apprehended by Secret Service Uniformed Division Officers."
No law enforcement personnel were injured during the incident and no shots were fired, the US Secret Service added.
Nearby traffic was affected in Washington D.C.
Eamon Havers, a Washington correspondent for CNBC, posted on Twitter: "White House has locked the press office doors, which are typically open all day.
"A few moments ago, I saw three uniformed Secret Service officers running toward the residence."
Noah Bierman, a White House reporter for the Los Angeles Times and Chicago Tribune, said the press room had since been opened.
Mr Turnbull remained at the White House while investigations took place.
