"This amendment does not extend or expand the food stamp program. It provides the exact same programs that families receive today," Gillibrand said ahead of the vote.
Gillibrand's is a number of food stamp amendments the Senate is considering for the farm bill. The other amendments, sponsored by Republicans, add limits to the food stamp program.
Just before the vote on Gillibrand's amendment, the Senate approved an amendment by Sen. Dianne Feinstein (D-Calif.) calling on studies of food safety recalls.
The Senate also voted down an amendment by Sen. Pat Toomey (R-Pa.) that eliminated a cost share assistance program for organic food.
