CARTEGENA - The Secret Service says it has placed 11 employees on administrative leave for misconduct in Colombia, where they were working on security ahead of President Barack Obama's trip to the South American country.
The agency's assistant director says the employees were both special agents and Uniformed Division officers.
None were assigned to directly protect Obama himself.
The agency did not disclose the nature of the allegations. The Associated Press confirmed that the behaviour in question involved prostitutes.
Obama is in Colombia for the Summit of the Americas. The Secret Service says it regrets any distraction the situation has caused during the regional meetings.
