Fairly straight forward, Senator Leahy has a petition and you can sign it if you are inclined to support establishment of a Bush Truth Commission.

From the Web site with the petition;

Support a Truth & Reconciliation Commission

8,466 signatures so far… keep it going! (As of the time this diary was written)

I have proposed the idea of a truth and reconciliation commission to investigate abuses during the Bush-Cheney Administration — so they never happen again. These abuses may include the use of torture, warrantless wiretapping, extraordinary rendition, and executive override of laws.

Please sign this online petition, urging Congress to consider establishing a truth and reconciliation commission to investigate the Bush-Cheney Administration’s abuses.

Thank you,

Patrick Leahy
U.S. Senator
