(CNN, May 6, 2014) – Officials temporarily locked down the White House late Tuesday afternoon due to a security situation at a street entrance to the complex, according to CNN journalists inside.
The move came after a vehicle followed a motorcade into a secure area at 4:40 p.m., a U.S. Secret Service spokesperson said.
The driver was stopped by uniformed officers at the outer perimeter of a checkpoint at 17th Street and Pennsylvania Avenue and taken into custody, according to the spokesperson.
About one hour after it began, journalists inside the White House were told the lockdown had been lifted.
Due to tight security at the home of the President, even minor breaches can bring a lockdown.
