Intruder Bypasses Secret Service to Enter National Security Adviser's Home

An intruder entered the home of Jake Sullivan, President Biden's national security adviser, in late April without agents guarding the house noticing.
Sullivan confronted the intruder and instructed him to leave; there were no signs of forced entry.
The Secret Service is investigating the security breach and implementing additional precautions.
The White House and officials are alarmed, as the Secret Service increased security for the adviser in 2021.
The agency has struggled with expanding responsibilities and past security lapses.
