WASHINGTON — The Secret Service told US lawmakers Thursday it is investigating new accusations of misconduct in El Salvador, where agents of a presidential advance team reportedly partied at a strip club and paid for sex.


"Earlier this week the US Secret Service received a call concerning the allegations," the elite presidential protection force said in a memo to lawmakers, a congressional source told AFP.

The explosive new allegations -- on the heels of the Colombia sex scandal that saw eight agents dismissed from the service and prompted a sweeping investigation -- were first reported Thursday by KIRO-TV.

It said a subcontractor "who worked extensively with the Secret Service advance team" was with the agents and some military specialists at a San Salvador strip club days before President Barack Obama's trip to the country in March 2011.

The subcontractor told KIRO he witnessed agents drinking heavily and that several of them paid for sexual favors from women in a VIP section of the club.

The Secret Service said in its note to lawmakers that it was seeking to interview the investigative reporter "in attempt to get any and all information he may have in an effort to verify the allegations," the congressional source said.
