From Patrick Poole's exclusive story at Big Peace:

Anwar Hajjaj is the former head of the Taibah International Aid Association, which was designated as terrorist organization by the U.S. government in May 2004. Al-Qaeda fundraiser Abdurahman Alamoudi, currently serving a 23-year prison sentence, was Taibah International’s vice president. When Alamoudi was arrested in 2003, prosecutors identified Alamoudi’s work with Taibah in court documents as evidence of his “material financial support” for al-Qaeda. Hajjaj was also a top official of the American office of the World Assembly of Muslim Youth (WAMY), which was raided in June 2004 and was co-founded by Osama bin Laden’s nephew, Abdullah bin Laden. He also the former education chairman of the Islamic Society of North America (ISNA), and the former president of the Dar-al-Hijrah mosque in Falls Church, Virginia. Dar-al-Hijrah is the mosque where Anwar al-Awlaki served as imam and at least two of the 9/11 hijackers attended services.

NATURALLY, then, as shown in the above happy-talk Roll Call video, Anwar Hajjaj is conducting prayers for the Islamic faithful of the Congressional Muslim Staff Association on Capitol Hill on April 16, 2010.

If your head hurts, that's a good sign.
