Missouri Sen. Chuck Graham pleaded guilty Friday to driving while intoxicated.
Graham was fined $500 and ordered to pay $122 in court costs on the misdemeanor charge.
Graham, a Columbia Democrat, was arrested Oct. 20 after his car rear-ended a vehicle at a stop sign and pushed it into a third vehicle.
He refused six requests to take a breath test. Graham could lose his driver’s license for a year for refusing the test. He is challenging the automatic suspension. A hearing is set for Jan. 10.
