SAN ANTONIO -- A vote on the 2018 Farm Bill is expected to hit the U.S. House floor this week.

But there's still a big sticking point over work requirements for food stamps - also known as the Supplemental Nutrition Assistance Program - or SNAP.

Leaders say cuts to SNAP could impact millions of Texans across the board. Proponents say the San Antonio Food Bank is an example of the program working.

"District 20, my congressional district, [includes] a big part of West and South San Antonio, but also almost all of Northwest Bexar County. That includes 35,000 households, just in District 20, that are part of the SNAP program. It includes 4 million Texans out of 42 million Americans who are served," said Rep. Joaquin Castro, D-San Antonio. 

Castro and Rep. Lloyd Doggett, D-Austin, are voicing their concerns over the cuts to SNAP in the 2018 Farm Bill. The bill would cut billions of dollars in SNAP benefits and includes strict requirements for those seeking assistance.

Many people benefiting from SNAP are elderly people and children. Being on SNAP allows children to have free breakfasts and lunches at school and during summer feeding programs.

One of the biggest points of contention over the bill is the requirement for people to keep a job, or go to job training classes. Otherwise they would risk losing their benefits.

"The worst thing about the work requirement, because you do have many people working, is many of these are low wage jobs in which the hours fluctuate and they're short term or seasonal. So if someone misses that period, gets the data wrong, loses a job, then they're found to have not met a requirement. They get cut off for an entire year," Doggett said.
