WASHINGTON (AP) - A senior Secret Service agent being formally investigated by the government for failing to disclose a long-standing relationship with a foreign citizen killed himself last week.
People familiar with the matter say Rafael Prieto, a married father assigned to President Barack Obama's security detail, acknowledged the affair after U.S. authorities began investigating. These people spoke on the condition of anonymity because they were not authorized to discuss Prieto's death or the investigation.
The sources say Prieto's relationship was revealed to Secret Service investigators by an agent who had been entangled in the Colombian prostitution scandal earlier this year. That agent was concerned that the Secret Service wasn't enforcing its rules consistently.
It is against Secret Service rules to have a relationship with a foreign citizen and not tell the agency.
