WASHINGTON — Two senior Secret Service agents were “more likely than not” impaired by alcohol when they drove a government vehicle through a secure area at the White House earlier this year, a government watchdog concluded.

Homeland Security Inspector General John Roth found that Marc Connolly and George Ogilvie spent about five hours at a bar during and after a retirement party for a colleague and ran up a “significant” bar tab before driving to the White House on March 4.

Connolly, the deputy special agent in charge of the Presidential Protection Division, announced his retirement in advance of the report’s release. Ogilvie, the assistant special agent in charge of the agency’s Washington field office, has been placed on administrative leave.

Both men denied being drunk and told investigators they only had a few of the drinks over the course of the night. Ogilvie said some of the drinks on his tab were given to other people, though he could not recall who.

Secret Service Director Joseph Clancy said Wednesday he was “disappointed and disturbed at the apparent lack of judgment described in this report. Behavior of the type described in the report is unacceptable and will not be tolerated.”

Roth’s report said Ogilvie was driving when his government-owned vehicle went into the secured zone where Secret Service officials were investigating a suspicious package.

Ogilvie pushed a larger construction barrier about 5 feet with the vehicle bumper.
