The White House was locked down Monday morning after a driver crashed into a security barrier in Lafayette Park and someone jumped over a White House barricade in a different location at about the same time, authorities say.
Secret Service agents ordered journalists to stay in the briefing room in the West Wing.
Video shot by Martin Austermuhle of The Washington Sun shows a smoking silver sedan on a brick walkway just north of the White House.
Secret Service officers appear to talk with the driver as National Guard troops stand by.
“Get on the ground!” someone is heard shouting as the driver clashes with officers.
“The driver was combative with law enforcement but was quickly placed under arrest,” the Secret Service said in a statement.
The D.C. police department’s bomb squad is searching the car as a precaution, the Secret Service said.
It wasn’t immediately clear why the driver crashed.
“Around the same time, a second individual jumped a barricade near the northwest corner of Lafayette Park. That individual was also quickly placed under arrest,” the Secret Service said.
The person who jumped over a barricade did so a short walk away, at Pennsylvania Avenue and 17th Street, a source familiar with the investigation said.
The White House was locked down for about 30 minutes before normal operations resumed.
