Muhammad Umar is a member of the Islamic Liberation Party, a radical Muslim organization that advocates bigotry against the practitioners of any faith other than Islam, and which seeks to overthrow secular government institutions throughout the Middle East. Umar has also spoken at rallies throughout the U.S. for The Islamic Committee for Palestine (ICP), which was established by Sami Al-Arian and was promoted as a philanthropic advocacy group devoted to alleviating the suffering of Palestinian woman and children; in reality, however, the ICP served as an American front for the amassing of funds for Palestinian terrorists abroad.
