It’s not clear from the public record how long he has served in the position. But his presence on the Vatera board indicates that he has a personal financial stake in the biopharmaceutical industry.

At the time of the biologics fight on Capitol Hill — which the industry won — Dean told Time that “I wouldn’t do this if I didn’t believe it.”

Dean has invoked the same argument when it comes to his work in support of the MEK, the Iranian militant group. Dean and other luminaries from across the political spectrum have been paid vast sums of money by the group — as much as $20,000 for a 10-minute speech — to appear at events pushing the Obama administration to remove the MEK from the official list of terrorist organizations. 

Dean himself has acknowledged being paid but has not disclosed specific sums.

Critics of the MEK, including the State Department, say the group displays cult-like qualities; it has been led by the same husband-and-wife couple, Masoud and Maryam Rajavi, for decades. They also point to the fact that it killed Americans in Iran in the 1970s and the lack of support for the group among the people of Iran. Among the most enthusiastic supporters of delisting MEK have been neoconservative strategists who believe the group can help destabilize the Iranian regime.

Dean, for his part, has been distinguished by his particularly aggressive advocacy for the MEK. Not only has he argued for delisting MEK in print and in speaking appearances, he has also said that Maryam Rajavi should be recognized as the president of Iran. The Christian Science Monitor reported on a recent trip by Dean to Berlin:

“Madame Rajavi does not sound like a terrorist to me; she sounds like a president,” Mr. Dean said, gesturing toward the MEK leader from the dais. “And her organization should not be listed as a terrorist organization. We should be recognizing her as the president of Iran.”

While Dean has passionately argued he is on the right side of the MEK issue, he acknowledged to the Washington Times that he got involved through his agent.

“I got asked by my agent to go over to Paris to speak to a group I knew nothing about. I spent a lot of time on the Internet learning about them, and then I met them,” he told the paper.

Dean spokeswoman Karen Finney said that, besides paid advocacy work, the former governor spends his time on a range of other activities, including appearing as a paid contributor to CNBC; traveling as a board member for the National Democratic Institute, which promotes democracy around the world; giving paid speeches; teaching a class at Hofstra University; and serving on the board of Extendicare, a Canadian long-term care company. Finney said he also continues to do some work for Democracy for America, a political action committee Dean founded that is run by his brother, Jim.

Whom else does Dean work for as a paid advocate?

In January, he waded into another high-stakes healthcare fight, this one being waged in New York state between foreign medical schools and their American competitors. The issue was whether foreign-trained doctors would have access to hospitals in New York for their residencies. Dean wrote an Op-Ed in the Albany Times-Union, “N.Y. needs its foreign-trained doctors,” that repeated talking points of foreign medical schools, which, Dean’s bio blurb noted, are clients of McKenna Long & Aldridge.

While the firm won’t say whom Dean has worked for, his bio page on McKenna’s website offers some clues.

“Respected for his fiscally moderate policies as Governor, he understands first-hand the severe budget constraints that are challenging state and municipal governments,” it reads. “With an extensive set of contacts nationally, Governor Dean is uniquely positioned to develop partnerships between industry stakeholders and local governments.”

Dean is indeed uniquely positioned: Between his former followers and his current clients, between his idealist liberal past and the cynical culture of K Street, between independence and cooptation.
