As pointed out in this article:
The Obama campaign maintains that the new HHS policy does not remove the work requirement. It called Romney’s statements untrue and hypocritical and noted that some Republican-led states had sought the new waiver policy.
“The Obama administration, working with the Republican governors of states like Nevada and Utah, is giving states additional flexibility only if they move more people from welfare to work – not fewer,” Obama campaign spokeswoman Lis Smith said in a statement emailed to reporters. She also noted that “as governor (of Massachussets), Mitt Romney petitioned the federal government for waivers that would have let people stay on welfare for an indefinite period, ending welfare reform as we know it, and even created a program that handed out free cars to welfare recipients.”
In 2005, Romney joined with 28 Republican governors to ask Congress for welfare waivers similar to those HHS authorized in July. “Increased waiver authority, allowable work activities, availability of partial work credit, and the ability to coordinate state programs are all important aspects of moving recipients from welfare to work,” the governors wrote in their letter to Congress.
