Homeland Security Secretary Janet Napolitano says the Homeland Security inspector general is supervising the Secret Service prostitution investigation and will "leave no stone unturned."
Napolitano told the Senate Judiciary Committee on Wednesday that the inspector general is using the investigative resources of the Secret Service in its probe of allegations that a dozen employees were involved in the incident at a Colombia hotel before President Barack Obama arrived for a South America summit.
There have been no reports of similar wrongdoing reported to the Secret Service Office of Professional Responsibility in the last 2 1/2 years, Napolitano said.
