Mitt Romney's claim that President Obama would "gut welfare reform" has been debunked by fact-checkers, but running mate Paul Ryan made the case for the campaign Thursday night.

“Read the law,” he told reporters on his plane. “The law does not reinstate the ability to waive the work requirements. When we passed the reauthorization of welfare reform, we tightened the work requirements to make sure it was actually getting people to work. And so, I believe the law does not allow that kind of flexibility, and that it undermines the spirit of welfare reform, which was to transition people from welfare to work.”

It was a rare bit of policy talk from Ryan, who has plied the traveling press with food but taken few questions.
