The U.S. military says five service members supporting the Secret Service in advance of President Barack Obama's visit may have been involved in inappropriate conduct and have been confined to quarters. Obama is in Colombia for a Summit of the Americas.
White House spokesman Jay Carney said the incident with the military personnel stems from the same episode involving about a dozen members of the Secret Service who were called back to the U.S. for an investigation into possible misconduct.
Carney referred questions about the episode, which includes allegations that U.S. personnel procured prostitutes, to the Secret Service and to the military.
Carney said the president retains confidence in the Secret Service and said the incidents under investigation, which preceded Obama's arrival, had no impact on presidential security.
