WASHINGTON D.C (WTVB) - The U.S. Senate is expected to approve a massive farm bill this evening. The legislation funds farm programs for five years and sets policies for agricultural subsidies and food aid. The House is expected to take up a farm bill later this month and a fight could be brewing with the Senate over food stamps. House Republicans want to make deep cuts in food stamp programs. Food stamp rolls have increased greatly in the past few years due to the recession and the sluggish recovery.
