Two of the Secret Service agents being ousted over a prostitution scandal in Cartagena, Colombia, were identified Thursday.

David Chaney was the supervisor who was allowed to retire, CBS News has learned. Supervisor Greg Stokes was removed with cause and has the option to appeal the decision within 30 days. He was recently listed on the Internet as the supervisor of the Canine Training Section of the Secret Service.

Attempts to reach both of them were unsuccessful.

A third, still unidentified, agent resigned in the wake of the scandal, CBS News first reported Wednesday. At least eight other Secret Service employees remain under investigation and further resignations are expected. Ten defense personnel are also under investigation for alleged involvement.

Meanwhile, congressional leaders expect more Secret Service agents could be forced out of their jobs soon, Reuters reported Thursday.

Reps. Darrell Issa, R-Calif., and Elijah Cummings, D-Md., chairman and ranking member of the House Oversight and Government Reform Committee, predicted on Thursday there would be more fallout from the scandal surrounding a night of partying by Secret Service agents and U.S. military personnel last week in the coastal city of Cartegena just before President Barack Obama arrived for the weekend Summit of the Americas.

The other eight Secret Service employees under investigation may also go, Issa said.

At the least, they will be reprimanded, dealt with administratively. At the most, they will depart. That's really something the investigation will decide, Issa told reporters outside the House.

It would not surprise me if there were within the next few days additional resignations or firings, said Cummings. Both Cummings and Issa have been briefed by Secret Service Director Mark Sullivan.

It is our understanding the resignations could come today or tomorrow, Rep. Peter King, R-N.Y., chairman of the House Homeland Security Committee, told the Los Angeles Times Thursday. He has been briefed by Sullivan as well.

The Secret Service and the Pentagon are conducting parallel investigations, including interviews with women believed to be prostitutes who were brought into Hotel Caribe, where the U.S. advance team was staying. Up to 21 women have been identified.

Officials have been able to find some of the women because they were required to leave personal identification at the front desk before they went up to the rooms.
