Secret Service Agent Fired in 2008 Prostitute Case Secret Service Director Mark Sullivan says an agent was fired in 2008 after being caught in a Washington prostitution scandal. Sullivan told a Senate panel that the on-duty agent was caught trying to hire an undercover police officer and was "separated from the agency" a month later. Sullivan is testifying before the Senate Homeland Security and Governmental Affairs Committee about the Colombia prostitution scandal that erupted after an officer and a Colombia prostitute argued over payment at a Cartagena hotel last month. In his first public statements about the scandal, Sullivan apologized for the employees' behavior.
