Three Secret Service personnel tied to Colombia prostitution scandal to leave agency The Secret Service announced late Wednesday that three of its personnel connected to the Colombia prostitute scandal -- two supervisors and one agent -- will leave the agency while eight more remain under investigation over the controversy. The agency is carrying out a full probe into the incident, including lie-detector tests and witness interviews in Colombia, the assistant director of the U.S. Secret Service Office of Government and Public Affairs, Paul Morrissey, said in a statement. "Although the Secret Service's investigation into allegations of misconduct by its employees in Cartagena, Colombia, is in its early stages, and is still ongoing, three of the individuals involved will separate or are in the process of separating from the agency," said Morrissey, whose office is running the probe. One supervisor was allowed to retire from the agency. Another "has been proposed for removal for cause," triggering a process in which that person can hire a lawyer and challenge the case against him. And one agent has resigned. "The remaining eight employees continue to be on administrative leave.Â Their security clearances remain suspended," Morrissey said. The Secret Service continues to conduct a full, thorough and fairÂ investigation, utilizing all investigative techniques available to ourÂ agency. This includes polygraph examinations, interviews with theÂ employees involved, and witness interviews, to include interviews beingÂ conducted by our Office of Professional Responsibility in Cartagena,Â Colombia," he said. Since these allegations were first reported, the Secret Service hasÂ actively pursued this investigation, and has acted to ensure thatÂ appropriate disciplinary action is effected. We demand that all of ourÂ employees adhere to the highest professional and ethical standards andÂ are committed to a full review of this matter," Morrissey said.
