Secret Service officials arrested two people outside the White House in separate incidents on Monday near Lafayette Square Park.
Video from the park circulating on social media showed a vehicle that appeared to run into a barrier, with the engine emitting smoke.
"Just before 10:00 a.m., Secret Service Police and National Guard responded to the north side of Lafayette Park at 16th Street and H Street, NW, where a vehicle crashed onto the sidewalk. The driver was combative with law enforcement, but was quickly placed under arrest," a Secret Service spokesperson said in a statement.
"MPD’s Explosive Ordinance Disposal team has been called to sweep the vehicle as a precaution. Subsequently, roads around Lafayette Park have been closed," the statement continued.
"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," it added.
The Secret Service briefly moved reporters and the press inside the White House briefing room after the incident, but they have since been released.
Authorities say both incidents are currently under investigation.
