A federal watchdog plans to send the U.S. Secret Service a formal warning Thursday about the security risks of overworking its employees — after discovering two Secret Service officers asleep at their posts, according to three government officials familiar with the findings. The Inspector General who oversees the Secret Service is expected to issue a management alert about the incident this week, as early as this afternoon. That formal designation indicates investigators have found a problem so urgent or sweeping that its requires swift attention from senior management.

The management alert stems from a routine check this August of alarms and communication equipment at facilities protected by the Secret Service, the three officials said. In the wake of radio failures when a fence-jumper got inside the White House in September 2014, auditors with the Department Homeland Security’s Office of Inspector General rode around to various sites with Secret Service staff. They found one officer at an embassy post and another stationed at the White House complex who appeared to be asleep while on duty. FULL REPORT
