Not less than 48 hours after MIT economist Jonathan Gruber apologized to a congressional oversight panel for his comments on Obamacare, opponents of the health-care law dug up a new video of Gruber telling a class he "helped write" the legislation.

"Full disclaimer: I'm going to describe it objectively, but I helped write it,” Gruber said during a class lecture about four years ago. “So I'll be objective. I'll try to be objective, but just full disclaimer, I was involved in writing the legislation, so there is some bias involved here."

Previously, Gruber distanced himself from the law when he became controversial, saying, " I was not the ‘architect’ of President Obama’s health care plan," as many reports had claimed.

As reported previously and as Gruber told Congress under oath on Tuesday, Gruber provided an economic model that helped the administration that produced quick cost estimates during the drafting of the law. He didn't actually write the law.

But the video will raise new questions from opponents of the law, who could keep the MIT professor in the news for months to come.
