ObamaCare architect mouths off again, as videos cause problems for Dems | Fox News.

"The mouth that won’t stop giving — and that has Democrats and the Obama administration cringing — has been caught shooting off yet again on video, this time bragging how the Massachusetts health care system he helped design worked by ripping off millions of dollars from the federal government.

On top of that, another video has surfaced from Vermont showing him mocking a critic of single-payer health care, comparing him to an "adolescent" child.

The latest videos of Jonathan Gruber come after House Democratic Leader Nancy Pelosi claimed Thursday she didn’t know who he is. Though Pelosi actually cited Gruber’s analysis — repeatedly — several years ago to boost the passage of ObamaCare, her office continued to insist he played no real role in the crafting of their bill.

Yet video after video has emerged of Gruber boasting about the behind-the-scenes crafting of the Affordable Care Act, and how law-writers supposedly took advantage of the "stupidity" of the American voter.

The latest videos pertain to state health overhauls, in Massachusetts and Vermont.

One video, from a January 2012 forum, shows Gruber discussing the Massachusetts overhaul under then-Gov. Mitt Romney. He explained how the state was able to bilk the feds over hundreds of millions of Medicaid dollars.

"The dirty secret in Massachusetts is the feds paid for our bill, okay?" he said. "In Massachusetts we had a very powerful senator you may know named Ted Kennedy. … Ted Kennedy and smart people in Massachusetts had basically figured out a way to sort of rip off the feds for about 400 million dollars a year."
