Van Jones has been wrongly savaged by rightwing commentators. Unfortunately, it turns out that Jones handed them his own head by signing a 2004 petition that embraced 9/11 conspiracy stuff about the Bush administration. (Kate Sheppard provides details.) This is politically damaging at a critical moment, and the petition was in every way indefensible. It is especially sad to see a worthy person make a career-damaging mistake. But Jones needs to man-up and leave quickly before further damage is done.
