BOISE -- U.S. Sen. Mike Crapo of Idaho is headed back to Washington, D.C., to participate in negotiations over averting the so-called fiscal cliff and doesn't plan to immediately provide details about what led to his arrest early Sunday on suspicion of drunken driving.
The Republican lawmaker's spokesman in Boise, Lindsay Nothern, said Crapo was traveling Wednesday after spending Christmas with family in Idaho Falls.
The three-term senator is accused of registering a 0.11 percent blood-alcohol level on a breath test after running a red light in Alexandria, Va., where the legal limit is 0.08.
Nothern says Crapo plans to eventually provide more information about his arrest. He provided no timeframe but indicated it could be several days.
Crapo, who is 61, faces a Jan. 4 court hearing.
