Senate Armed Services ranking member John McCain (R-Ariz.) ripped the Defense Department today after receiving a briefing with “appallingly little new information” about the investigation into the prostitution scandal enveloping the Pentagon and the Secret Service.

McCain said he and Armed Services Chairman Carl Levin (D-Mich.) asked for the briefing to inquire about the national security implications from the incident in Cartagena, Colombia.

“Unfortunately, nearly two weeks after the events in Colombia, the briefers sent by the Department of Defense were woefully unprepared to answer even the most basic questions about what happened in Cartagena and provided appallingly little new information other than the mechanics and timeline of the ongoing investigation,” McCain said in a statement. “The Department of Defense briefers did not even know the date the president arrived or the name of the senior military commander on the ground in Cartagena.”

McCain called the briefing “entirely unacceptable.”

“We need to know the facts. We need to know the impact of this potential misconduct — which occurred less than a day, or perhaps hours, before the president arrived in Cartagena — on the performance of the military Joint Task Force charged with his security.”
