As many as six US Secret Service employees have been fired so far in the Colombian prostitute scandal that came to light after a high-end escort refused to leave the premises till an agent paid her $800 for the services.

The rest of the eleven-member secret service contingent who got embroiled in the scandal are on administrative leave. The action was taken after it was reveald that around 20 Colombian hookers were brought to their hotel on April 11, during a Presidential visit. 

The “serious misconduct” of government employees caused much embarrassment to President Barack Obama and completely tarnished his major at an international summit in Cartagena.

More than 20 US military agents, including two supervisors, were accused in the scandal. The investigators who probe the Cartagena incident say that more employees could lose their jobs or face strict administrative actions in near future.

“I would think you'll see most of the 11 either resign, retire or will be forced to leave,” Homeland Security Committee’s representative Peter King said.

According to a Daily Mail report, the head of the Homeland Security Committee investigating the case has asked the agents to explain the reckless behavior. 

King has ordered a meticulous investigation and demanded to know the names of the accused. He doubts if the agents had any weapons or classified material in the room where the women were brought in, and is probing the matter.

“We want a full record, so at the end we can decide if the Secret Service acted appropriately once they found out about it,” King said, imposing a deadline on director Mark Sullivan for the information, according to Fox News.

Most importantly, King has also demanded to know if federal fund was misused to pay the hookers, the report said.

... How many agents paid the women, and how many provided monetary remuneration to the female foreign nationals involved in the alleged incident in Colombia with the per diem provided by the U.S. government? asks King, according to Fox News.

“I doubt, no matter what happens, you're going to see any of these 11 ever involved in any kind of detail like this again,” he said.

Referring to the two supervisors involved in the misconduct, King said: “They should have been in control of everything. Instead, they were accessories. They were part of it.”

Every possible lead is being examined, the administration needs to have a zero-tolerance policy, he added.

Earlier this week, Iowa’s senior senator Chuck Grassley said: “If the culture of an organization is going to change or mistakes like this are not going to be repeated, heads have to roll and that is why I think you are going to find more heads rolling.”
