Intrusion at the home of national security adviser under investigation, U.S. official says

Sullivan confronted the intruder, who appeared to be intoxicated, and told him to leave, The Post reported. There was no sign of forced entry, and there was no evidence that the man knew Sullivan or had come to the home to harm him, The Post said, citing anonymous sources who were briefed on the episode.

The invasion is concerning, the Secret Service told The Post.

“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,” Secret Service spokesman Anthony Guglielmi told The Post in a statement. “Any deviation from our protective protocols is unacceptable and if discovered, personnel will be held accountable.
