It is possible – but not certain – that the framework for the potential new farm bill will be released this week. Even then the proposal will face several steps before it becomes law. Funding for the SNAP program has been an area of disagreement for months now with the House bill cutting $40 billion over 10 years versus the Senate bill’s cut of $4 billion.

It appears that the farm bill negotiators have settled on cuts of about $9 billion but there is still a lot of uncertainty about whether this level of cuts can pass in either the House or the Senate. House Majority Leader Eric Cantor says the farm bill will have to include provisions requiring the able-bodied to seek work or perform public service to be eligible for food stamps.
