Secret Service investigating intruder at National Security Advisor Jake Sullivan's home

The Secret Service is investigating a late April intrusion into the home of national security advisor Jake Sullivan's Washington, D.C., home that occurred despite the agency's providing Sullivan with round-the-clock protection.

Sullivan indicated to investigators that he encountered the person in his home and that he believed the intruder to have been intoxicated, The Washington Post reported. The intruder made no threat against Sullivan and that the individual managed to leave Sullivan's home without alerting the Secret Service detail.

Sullivan reportedly did not notify his security detail until after he asked the intruder to leave. Officials discovered no signs of forced entry.

Secret Service spokesman Anthony Guglielmi said that the agency "is examining a security incident that took place at a protectee site. While the protectee was unharmed, we are taking this matter seriously and have opened a comprehensive mission assurance investigation to review all facets of what occurred."

"Any deviation from our protective protocols is unacceptable and if discovered, personnel will be held accountable," he added. "Modifications to the protective posture have also been made to ensure additional security layers are in place as we conduct this comprehensive review."
