The Secret Service scandal has spread to a second hotel in Cartagena, Colombia -- the hotel where the president of the united states was staying while he attended a Latin summit April 12-14.
CBS News correspondent Whit Johnson reports that a law enforcement official told him a 13th agent is under investigation for bringing a prostitute back to the swanky Hilton Hotel where President Barack Obama was staying.
Until now, the investigation had been confined to one hotel, where 12 members of the uniformed division of the Secret Service are accused of partying with as many as 20 prostitutes.
Government officials had been confident that the president's safety was never at risk since the scandal didn't involve his first line of protection: the elite presidential detail.
"Now you're into the hotel where the president of the united states was going to stay, and it just gets more troubling," Sen. Joe Lieberman said on "Face the Nation."
Several lawmakers have called for an expanded investigation into the scandal, including pulling hotel records at the hotel where the president was staying.
So far 6 agents have been fired or forced to resign from the Secret Service in the past week.
Despite the fact that his elite agents are now involved in the scandal, President Obama continues to voice his support for Secret Service Director Mark Sullivan.
