(CNN) If Congress won't make more food stamp recipients work for their benefits, the Trump administration will.

The US Department of Agriculture unveiled a proposed rule Thursday that would expand work requirements in the Supplemental Nutrition Assistance Program, or SNAP, as the food stamp program is formally known. The proposal comes on the same day as President Donald Trump plans to sign a farm bill that had a similar provision that was eventually eliminated

The overhaul marks the administration's latest effort to impose work requirements in government assistance programs. In an unprecedented move, it has started allowing states to mandate that Medicaid recipients find employment. Administration officials point to the nation's low unemployment rate as a reason to push more Americans to self-sufficiency.

"A central theme of the Trump administration has been to expand prosperity for all Americans, which includes helping people lift themselves out of pervasive poverty," said Agriculture Secretary Sonny Perdue, noting it will save $15 billion over 10 years. The proposed rule "restores the dignity of work to a sizable segment of our population, while it's also respectful of the taxpayers who fund the program."

The food stamp program already requires non-disabled, working-age adults without dependents to have jobs. They can only receive benefits for three months out of every 36-month period unless they are working or participating in training programs 20 hours a week.
