The gray Honda sedan followed the motorcade—which conflicting sources claim was either transporting the Obama daughters home from school or ferrying Secretary of State John Kerry to a scheduled meeting with the president—reportedly running a roadblock and driving onto a restricted section of Pennsylvania Avenue where it was stopped by federal agents.
The male driver was arrested and the car was checked for explosives.
According to CNN, a source familiar with the incident claims the driver holds a pass for the U.S. Treasury building, a neighboring building.
All reporters were moved into the press briefing room and asked to remain while the Secret Service staged on the North lawn, according to the Washington Times.
No word on the driver’s intentions but an hour after it began, journalist were told the lock down had ben lifted.
