President Obama has downplayed Jonathan Gruber's role in the creation of the Affordable Care Act, calling him "some adviser who never worked on our staff."

Gruber created a controversy when several videos surfaced in which he admitted that the administration had to be deceptive about the ObamaCare proposals so that the bill would pass. 

Speaking from Australia this weekend, Obama challenged the press to go back through "every clip, every story" on ObamaCare, disputing that there was anything about the law that was not transparent. 

On "Special Report," Bret Baier did indeed take a look back, highlighting several issues with transparency when it comes to Gruber.

In a piece on liberal blog Firedoglake, Jane Hamsher wrote in 2010 about how the administration touted Gruber's supportive analysis without disclosing that he was being paid by HHS. 

Bret noted that it wasn't long after Gruber's $400,000 HHS contract went into effect that he was being cited widely by ObamaCare supporters on Capitol Hill. 

At a hearing, then-Sen. John Kerry (D-Mass.) called Gruber "our guide on a lot of this" and Nancy Pelosi referred to him by name.

When Gruber released his analysis of the House health care proposal, it was picked up by the Washington Post, and that article was then linked from the White House's blog in Nov. 2009. 

The White House post referred to Gruber's predictions of lower premiums and help for small businesses as "objective analysis." 

Again, no mention there that Gruber was under contract with HHS.

When the Senate put out its health care reform proposal two weeks later, Gruber's analysis was used by Atlantic magazine in a piece by Ron Brownstein.

 

"You couldn't have done better than they are doing," read a quote from Gruber in that piece, entitled "A Milestone in the Health Care Journey."

Bret noted that from there, the Brownstein piece was touted by the DNC and according to Politico at that time, Obama himself termed the article "mandatory reading" in the West Wing. 

Then Gruber's name was back on the Senate floor, with Harry Reid pointing to a piece written by Gruber in the Washington Post.

The article was headlined, "'Cadillac' tax isn't a tax -- it's a plan to finance real health reform," and at the end, Gruber was identified as a "professor of economics at the Massachusetts Institute of Technology."

In one of the videos that has now surfaced, Gruber admitted that the Cadillac tax was indeed a tax and intentionally mislabeled.
