"He kept saying over and over again that he basically does think this was an isolated incident and I don't think he has any basis for that conclusion," said Sen. Susan Collins of Maine, the senior Republican on the Homeland Security panel that heard Sullivan's first public accounting of the episode.
"For the good of the Secret Service," added Sen. Joseph I. Lieberman of Connecticut, the panel chairman, "he's got to assume that what happened in Cartagena was not an isolated incident or else it will happen again." Still, Sullivan insisted repeatedly that in his 29-year Secret Service career he had never heard anyone say that misconduct was condoned, implicitly or otherwise.
"I just do not think that this is something that is systemic within this organization," Sullivan said.
The misconduct became public after a dispute over payment between a Secret Service agent and a prostitute at a Cartagena hotel on April 12. The Secret Service was in the Colombian coastal resort for a Latin American summit before Obama's arrival. Twelve employees were implicated, eight of them ousted, three cleared of serious misconduct, and one is being stripped of his security clearance. Sullivan said two who initially resigned now are fighting for their jobs back.
"These individuals did some really dumb things," Sullivan told the Senate panel. "I'm hoping I can convince you that it isn't a cultural issue."
He didn't make much progress on that front, as senators offered fresh evidence of what they considered reckless behavior. Lieberman said that 64 allegations or complaints of sexual misconduct were made against Secret Service employees in the last five years.
Three of those, Lieberman said, were complaints of inappropriate relationships with a foreign national and one of "nonconsensual intercourse," on which he didn't have enough information to elaborate. Sullivan said that complaint was investigated by outside law enforcement officers, who decided not to prosecute.
Thirty other cases involved alcohol, Lieberman said, almost all relating to driving under the influence.
Sullivan also told the committee that an agent was fired in a 2008 Washington prostitution episode, after trying to hire an undercover police officer.
Charles Edwards, the inspector general at the Homeland Security Department conducting his own probe, and Sullivan discussed an episode from the 2002 Olympics when at least three agents were caught in a rowdy, drunken party in the agents' hotel rooms with college-age women under 21, the legal drinking age.
The agents involved left the Secret Service, Edwards and Sullivan said.
