Sheikh Abdul Hadi Palazzi, a vociferous critic of CAIR (and also of Palestinian terrorism), outlines in an article,
"Antizionism and Antisemitism in the Contemporary Islamic Milieu", the origins of CAIR and other similar movements, and explains how they are controlled by the Ikhwan al-Muslimeen i.e. Muslim Brotherhood - a global Islamist movement that originated in Egypt.
The Council for American-Islamic Relations (CAIR) is an organization that was created and is controlled by the Brotherhood; it works in the United States as a lobby against journalists, media operators, movie producers, etc. who dares to write things that do not fit their limited interpretation. ------Thanks to MuslimPundit for the link.
