Washington (CNN) - The U.S. Secret service may have swiftly determined the fate of a dozen of its members caught up in the prostitution scandal in Cartagena, Colombia, but spokesman Edwin Donovan tells CNN their investigation is not over.
“We still have folks on the ground in Cartagena,” Donovan said.
One day after president Obama praised the agency on “Late Night with Jimmy Fallon,” but referred to those involved in the scandal as “knuckleheads,” USSS investigators are still working to piece together more details.
“Interviews and corroborative interviews continue,” Donovan said.
Nine of the twelve service members who were under investigation have left or are being forced out of the agency.
In a statement Tuesday, Assistant Director Paul Morrissey stressed their commitment to conducting a thorough investigation and vowed the agency would “not hesitate to take appropriate action should any additional information come to light.”
