Ben Smith contacted another signer of the petition, Rabbi Michael Lerner:

I was asked to sign a letter which I was told had four demands:

As Americans of conscience, we ask for four things:

1. An immediate investigation by New York Attorney General Eliot Spitzer
2. Immediate investigation in Congressional Hearings.
3. Media attention to scrutinize and investigate the evidence.
4. The formation of a truly independent citizens-based inquiry.

I did not authorize my name to be used for all the other stuff that I now see was included surrounding the letter, namely the sponsors of that 911truth.org, and would not have had I been aware that all that stuff was presented in ways that suggested that I agreed with it, and though I do recognize a few of the people I’d consider “nut cases” among the list of signatories, my guess is that most of those who signed were, like me, unaware of the context in which our names would appear.

Gee- the troofers weren’t honest? What a surprise.
