The House is taking up a politically charged bill that would prevent the Obama administration from waiving any work requirements in the landmark 1996 welfare reform law.
House Republicans are using the bill to renew a political fight that started during the presidential campaign. They say President Barack Obama is trying to gut work requirements in the law - a claim that is disputed by administration officials.
The House is scheduled to vote on the bill Wednesday, though it has little chance in the Democratic-controlled Senate.
Last summer, the Obama administration announced it would be willing to grant states waivers of some of the law's requirements - but only if governors can show they will move at least 20 percent more people from welfare to work.
