Two senior Secret Service agents returning from a party drove a government car through police tape and barricades into an area where their colleagues were investigating a suspicious package, the Washington Post reported on Thursday.
The White House and the Secret Service have not commented directly on the incident.
It is under investigation by an internal supervisory group at the Department of Homeland Security.
This incident comes on the heels of a series of scandals for the agency that protects the president and his family.
President Obama was “disappointed to hear the allegations” earlier this week, White House spokesman Eric Schultz told reporters.
The Washington Post said the agents — one a top member of Obama’s protective detail and the other a senior supervisor in the Washington field office — drove to the White House just before 11 p.m. on March 4 after a party at a bar.
They drove through an area marked off with police tape where their colleagues were investigating a package thrown out of a car by a woman who had shouted, “It’s a bomb,” the newspaper said, citing a police report.
The officers drove very close to the item, which later was found to be a book wrapped in a green shirt, and may have even driven over it, according to the newspaper, citing interviews with investigators who reviewed surveillance video.
Secret Service officers on duty suspected the agents were drunk, but a supervisor let the agents go home, the Post reported.
