According to Del Ray, VA Patch, Crapo was pulled over after an officer saw the senator run a red light. Police spokesman Craig T. Fifer said that Crapo failed "several field sobriety tests," reports CBS News. He was taken into custody "without incident."
Patch reports that the Republican Senator was later released on an unsecured $1,000 bond. He will have to appear in court on January 4th.
Crapo is slated to take the top GOP spot on the Senate Banking Committee. He is also a member of the so-called "Gang of Eight," which CBS News describes as "a bipartisan group of senators who came together to work on a budget deal to avoid the upcoming 'fiscal cliff.'"

I accept total responsibility and will deal with whatever penalty comes my way in this matter.
"I will also undertake measures to ensure that this circumstance is never repeated."
