Arkansas U.S. Rep. Tom Cotton was the only member of the state's all-Republican House delegation to vote against a nearly $100 billion-a-year farm bill passed by the House on Wednesday.
U.S. Reps. Rick Crawford, Tim Griffin and Steve Womack all supported the measure, which passed the House on a 251-166 vote Wednesday.
Speaking on the House floor Wednesday, Womack said the farm bill begins the process of making "much-needed reforms to federal programs."
Cotton said earlier in the day that the farm bill didn't do enough to cut the food stamp program.
Cotton is challenging Democratic U.S. Sen. Mark Pryor, who has criticized the Republican for opposing earlier versions of the farm bill. Pryor has said he supports the latest measure.
