Republican Mitt Romney's campaign is renewing its criticism of President Obama's changes to welfare.
Romney's campaign is launching a new television advertisement accusing Obama of "gutting welfare reform." The ad says Romney would "put work back in welfare."
Romney says Obama lifted a provision that required people receiving welfare to work. The White House says Romney's assertions are false.
Obama moved last month to allow states to seek waivers from some welfare rules if they show that doing so results in better outcomes. Conservatives fear the waivers will lead to an end of the work requirement.
The Romney campaign did not say which states the ad would run in. The campaign says Romney will press the welfare issue during a town hall in New Hampshire Monday.
