A senior Secret Service agent who was being investigated by the government for failing to disclose a long-standing relationship with a foreign citizen killed himself last week in Washington, people familiar with the matter told The Associated Press.
Rafael Prieto, a married father assigned to the security detail for President Barack Obama, had acknowledged to U.S. investigators that he had been having an affair for years with a woman from Mexico, these people said. They spoke on condition of anonymity because they were not authorized to discuss Prieto's death or the investigation.
