Okay so here’s the bit from Tapper/ABC News on Van Jones:

In a statement issued Thursday evening Jones said of “the petition that was circulated today, I do not agree with this statement and it certainly does not reflect my views now or ever.”
He did not explain how his name came to be on the petition. An administration source said Jones says he did not carefully review the language in the petition before agreeing to add his name.

This strikes me as not even remotely plausible. Jones has been a creature of the leftist swamps for years. Here are some of his career highlights:

• Rose from the Oakland, Calif., grassroots organizing scene to become a leader in the national movement to spur the green economy.
• Started his career as a prison-reform advocate in Oakland lobbying for reform of the juvenile justice system and youth-violence prevention programs.
• Co-founded a socialist collective, Standing Together to Organize a Revolutionary Movement, or STORM, in 1994, which held study groups on the theories of Marx and Lenin and dreamed of a multiracial socialist utopia. The group protested police brutality.
• Co-founded the Ella Baker Center for Human Rights in 1996 and Color of Change in 2005, which includes Bay Area Police Watch, a group devoted to “protect(ing) the community from police misconduct.”
• Founded Green For All, an organization focused on creating green jobs in impoverished areas.
Published New York Times bestseller, “The Green Collar Economy: How One Solution Can Fix Our Two Biggest Problems,” in October 2008.
• Has law degree from Yale University.
• Worked on the Green Jobs Act in 2007 with then-Rep. Hilda Solis, D-Calif., who co-sponsored the bill in the House.
• Was arrested in San Francisco in 1992 after a protest march that followed the acquittal of police officers in the Rodney King beating. Jones was working with the Lawyer’s Committee for Civil Rights in San Francisco.
• Was arrested in the 1999 Seattle protests against the World Trade Organization

Now, Van Jones clearly speaks to lefty audiences all the time. He organizes the lefty rabble. Fueling resentments is his calling. He goes to lefty confabs and learn-ins, he’s comfortable shaking hands and finding common cause with coffee house Maoists and has no doubt saluted the entire parade of horribles that perambulate the furthest fringes of the flaky Left.

Now, the idea that he didn’t know what 911Truth.org was when he signed the petitition is remotely, faintly, ever-so-slightly plausible if one is willing to give the man a lifetime supply of benefit-of-the-doubt. The idea that he didn’t learn the truth after years slogging through these swamps, talking to Truthers, getting invitations and emails from Truthers, is just the most high-octane balderdash currently on offer.
