Senate Homeland Security Chairman Joe Lieberman (I-Conn.) announced Sunday that he will hold the first hearings on the Secret Service prostitution scandal this month.
"On May 23, at which we're going to have Director Mark Sullivan of the Secret Service and the acting inspector general of the Department of Homeland Security, Charles Edwards," Lieberman said on CNN's "State of the Union."
"One is, is the inspector general satisfied with the investigation of what happened at Cartagena that the Secret Service did? Secondly, were there indications before the Colombian scandal of behavior by Secret Service agents off duty, on assignment, that should have been a warning that this was coming? And then, third, what are you going to do, Director Sullivan, to make sure that nothing like this ever happens again?" Lieberman said.
"This is really a heartbreaking incident, and really a dangerous incident, and we really have got to make sure it never does happen again," he added.
Close to two dozen agents have been implicated in the scandal.
