The denouement:

“That is false, in a variety of ways. I don’t believe that it’s substantively true,” Noam Scheiber, author of The Escape Artists, told TPM by phone Thursday morning.

On Wednesday Romney said President Obama and his aides believed the health care reform law would harm the recovery but pushed for it anyway, and sourced the argument to Scheiber’s book. But the claim is not true.

“There are a couple of claims wound up together there in Romney’s remarks,” Scheiber said. “One claim is that [Obama’s team] knew that the Affordable Care Act itself — something about the Act — would derail the recovery…. They do not believe that it’s substantively true. So it’s not something that they felt, and it’s not something I argue in the book.”

Will Romney retract? Will any journalist ask him to? I wouldn't hold my breath on either of those scenarios. The lie is dissected here.
