Republican lawmakers are preparing plans to restructure America's welfare system, including putting new limits on who's eligible for anti-poverty programs such as food stamps and housing benefits.

The details of the planned overhaul are still being determined, but congressional Republicans have already introduced policy proposals that would impose new work requirements on some of America's welfare programs. Last year, House Ways and Means Committee Chairman Kevin Brady (R-Tex.) and House Speaker Paul D. Ryan (R-Wis.) unveiled a poverty plan as part of Ryan's “A Better Way” agenda, which also called for the imposition of new work requirements.

The plans at the time were largely markers of future intention, signaling the party's vision but not indicative of an imminent push for legislative action. Now, as they enter the final stages of completing an overhaul of the U.S. tax code, GOP leaders are suggesting that push is on the way.

“Last year, Ways and Means Republicans laid out our vision for reforming our nation’s welfare system so Americans can move off of welfare and successfully into the workforce,” said Brady, whose committee is expected to take the lead on tax reform. “We are committed to working with President Trump to turn our vision into a reality.”

Another proposal likely to be widely discussed is a bill introduced in June by Sen. Mike Lee (R-Utah) and Rep. Jim Jordan (R-Ohio) that puts new work requirements on food stamp and direct welfare beneficiaries. The Lee-Jordan bill would also cut federal responsibility for paying for federal housing assistance, and call on the states to provide half of the program's funding within 10 years.

A spokesman for Ryan said that the party would decide its next big priority at its policy retreat in January.

On Tuesday, the Wall Street Journal reported White House officials have prepared an executive order that would set principles for Congressional-led welfare overhaul, as well as issue instructions for federal agencies to enact new welfare regulations.

“We’re looking very strongly at welfare reform, and that’ll all take place right after taxes, very soon, very shortly after taxes,” Trump said at the White House in November, one of several times recently he has suggested a coming attempt to change the social safety net.

“Does anyone want welfare reform? And infrastructure,” Trump said last week in Missouri. “But welfare reform, I see it, and I've talked to people. I know people that work three jobs and they live next to somebody who doesn't work at all. And the person who is not working at all and has no intention of working at all is making more money and doing better than the person that's working his [or] her ass off. And it's not going to happen.”

In March, Trump released a 2018 budget proposal that would have cut $610 billion from Medicaid, the health program that primarily covers poor Americans, as well as hundreds of billions of dollars in welfare cuts.

Republicans face significant challenges in changing the social safety net, especially ahead of the 2018 midterm election season, when Democrats will attempt to capitalize on Trump's current low approval ratings to take back power in Congress. The party has also only a slim majority in the Senate, meaning it would have to unite the party's most moderate and conservative members behind a single plan. Such ideological divisions partly sunk multiple efforts to repeal large parts of the Affordable Care Act.

“People who go to work on that 5 a.m. bus and try to put food on the table — somehow these people are scamming the government? Really? Really? It’s so offensive to me,” said Rep. Jan Schakowsky (D-Ill.), a member of the House Budget Committee. “These are the people they want to go after? It’s just astonishing for me that this is where they want to go in the context of this tax bill — the biggest shift from middle class to the wealthy we have ever seen in this country. Shame on them.”

Academic experts said Republicans appeared to be preparing to attack a problem that does not exist. “It’s not as though there’s a bunch of cash sitting out there propping up low-income families,” said James Ziliak, director of the center for poverty research at the University of Kentucky. “What's the big pool of welfare for people who are selectively out of work?”

Republicans are most likely to try changing food stamps, the Earned Income Tax Credit and disability payments made through Social Security, according to Brian Riedl, a senior fellow at the Manhattan Institute.

“There’s a lot of concern among Republican offices that Americans with disability insurance is growing at an enormous rate, which is hard to explain in an economy where there’s less backbreaking work,” Riedl said, citing recent conversations on Capitol Hill. “I also hear a lot of concern that while poverty is up 30 percent, enrollment in food stamps is up 150 percent since 2001.”

But Ziliak, of the University of Kentucky, noted that food stamp enrollment has fallen from 47.4 million beneficiaries in October 2013 to 41 million this year.
