The Pentagon announced Monday that the Secret Service scandal that overshadowed President Obama’s trip to the Summit of the Americas in Colombia may involve more agents than originally thought. “We believe there are more than five [agents],” a spokesman said. Eleven agents have been suspended in connection with the case as Secretary of Defense Leon Panetta promised a full investigation. Agents are believed to have missed their curfew in Cartagena and brought prostitutes back to the hotel where the president was set to arrive a day later. President Obama said he would be “angry” if the accusations turn out to be true.
