WASHINGTON — A bitterly divided House panel Wednesday approved new work and job training requirements for food stamps as part of a five-year renewal of federal farm and nutrition policy.

The Republican-run Agriculture Committee approved the measure strictly along party lines after a contentious, five-hour hearing in which Democrats blasted the legislation, charging it would toss up to 2 million people off food stamps and warning that it will never pass Congress.

The hard-fought food stamp provisions would tighten existing work requirements and expand funding for state training programs, though not by enough to cover everybody subject to the new work and training requirements.

Agriculture panel chair Michael Conaway said the provisions would offer food stamp beneficiaries “the hope of a job and a skill and a better future for themselves and their families.”

At issue is the Supplemental Nutrition Assistance Program, or SNAP, which provides food aid for more than 40 million people, with benefits averaging about $450 a month for a family of four.

The food stamp cuts are part of a “workforce development” agenda promised by Republican leaders such as Speaker Paul Ryan, R-Wis.
