Secret Service Investigating Unauthorized Intruder at Home of White House National Security Adviser Jake Sullivan

The Secret Service is investigating an incident in which an unknown man managed to slip undetected into the home of White House National Security Adviser Jake Sullivan in the middle of the night a few weeks ago. According to two people familiar with the incident, the door was apparently unlocked and the intruder was able to get inside Sullivan’s home around 3 a.m. last month.

The Secret Service is looking into whether the person intentionally went into the home or whether it was some kind of accident; the person appeared to be intoxicated, the people said.

In response to the incident, the Secret Service has opened a comprehensive mission assurance investigation to review all facets of what occurred. The agency is also looking into “a security incident that took place at a protectee site.”

The Secret Service has also made modifications to the protective posture to ensure additional security layers are in place. Spokesman Anthony Guglielmi said in a statement that “while the protectee was unharmed, we are taking this matter seriously.”

The Secret Service is continuing to investigate the incident and is working to ensure that similar incidents do not occur in the future. The agency has not released any further information about the intruder or the incident.
