The Secret Service is investigating an incident in which an unknown man entered the home of White House National Security Adviser Jake Sullivan in the middle of the night a few weeks ago. The person appeared to be intoxicated and the Secret Service is looking into whether the person intentionally went into the home or not. The agency has opened a comprehensive mission assurance investigation to review all facets of what occurred and has made modifications to the protective posture to ensure additional security layers are in place.
