A man is in custody after an incident at the White House.
The Secret Service says access to the White House was halted for about an hour after a vehicle followed a motorcade in through the gates.
Uniformed Secret Service agents immediately stopped the vehicle after it trailed in behind the motorcade at about 4:40 p.m. EDT.
The driver, a middle-aged man, is in police custody. District of Columbia police swept the vehicle for explosives and restored access about an hour later.
