WASHINGTON -- Secret Service officers have subdued two men who refused to get out of the street as President Obama's motorcade was returning to the White House.

Secret Service spokesman Ed Donovan says Obama was returning Thursday night from a school event for one of his daughters when the men refused to move out of the way of the presidential motorcade. A uniformed Secret Service officer was seen lying on top of one man and another officer wrestled with the second man.

Donovan says the men, who were using profanity, were charged with assaulting a police officer and failure to obey a lawful order. He didn't have their identities.

Donovan says the incident appeared to be a random event and not an organized attempt to block the president's motorcade.
