WASHINGTON (TIP): The US Secret Service said on March 11 that two agents were under investigation after an incident last week in which they were reported to have driven a government car into White House barricades after drinking at a late-night party.

The Washington Post reported on Wednesday that one of the agents involved in the alleged March 4 incident was a top member of President Barack Obama‘s protective detail.

The Post quoted current and former government officials familiar with the incident as saying officers on duty wanted to arrest the agents and give them sobriety tests. But a supervisor ordered the agents be sent home, the officials told the paper.

A Secret Service spokeswoman said in a statement the agency was aware of the allegations against the two agents and that “if misconduct is identified, appropriate action will be taken based on established rules and regulations.”
