Colombia sex row claims more secret agents
Two more US Secret Service agents have resigned in the wake of the Colombia sex scandal, the agency has confirmed, BBC reported.
In addition, two other agents will face administrative action after being cleared of serious misconduct, and one has had security clearance revoked.
The moves follow the resignation of six others found to be involved in a night with alleged prostitutes while working in Colombia for a pan-American summit.
President Barack Obama earlier described the agents as "knuckleheads."
Speaking at a recording of an NBC chat show, Late Night with Jimmy Fallon, Mr Obama said the vast majority of Secret Service agents performed their duties with no hint of controversy.
"These guys are incredible. They protect me. They protect Michelle. They protect the girls. They protect our officials all around the world," Mr Obama said.
"A couple of knuckleheads shouldn't detract from what they do. What these guys were thinking, I don't know. That's why they're not there any more."
