A self-described terrorist, who has invoked revolution against our government, attacked innocent Americans in Arizona, including a representative to our Congress, a federal judge on our court and 10 others. This attack falls inline with the repeated call to arms we've heard from too many public figures on the fringe. An attack on one who serves is an attack on all who serve, as Speaker Boehner said in his statement. Now for the sake of our democracy, Congress has a duty to investigate any operative, commentator or group who may be giving aid and comfort to domestic enemies with anti-democracy hostilities. Tell Congress, Hold Hearings -- Sign this Petition.
