Top House appropriators called Tuesday for the Secret Service to immediately slap down disciplinary action and open its own investigation into allegations that two senior-level agents drove into a White House barricade while drunk earlier this month.

Secret Service Director Joseph Clancy testified before the House spending panel’s Homeland Security Subcommittee less than a week after lawmakers got word of the incident, and said he plans to wait for the Homeland Security Department’s inspector general wraps up its investigation ibefore he takes action beyond his decision to transfer the officers out of supervisory roles.

But lawmakers from both sides of the aisle urged the director to start taking steps toward firing the agents involved, suggesting the agency is trying to buy time and deflect scrutiny by waiting on the IG’s investigation.

“Needless to say, we want to get to the bottom of it right away,” said Rep. Harold Rogers, R-Ky., chairman of the full committee. “To say you’re not investigating because you want the inspector general of the department to investigate is hogwash.”
