Investigation launched after intruder enters home of White House national security advisor.

An "intoxicated" man entered the Washington home of National Security Adviser Jake Sullivan in the middle of the night, going unnoticed by his Secret Service detail. Sullivan confronted the intruder and asked him to leave before alerting his security detail. The Secret Service has launched an investigation into the incident and has made modifications to the protective posture. There is no evidence that the intruder knew Sullivan or sought to harm him. This is the latest security breach against the agency assigned to protect President Biden and other top US officials.
