Republican Senate candidate in California Tom Campbell is the frontrunner in the nomination fight and his ties to radical Muslims, specifically Sami al-Arian, have become an issue, but the story is bigger. Campbell has surrounded himself with people tied to the Muslim Brotherhood, who recruited him for their political agenda in a campaign that ultimately reached the Bush White House.
In November 2001, a Brotherhood document called "The Project" from 1982 was found by Swiss police raiding the home of Youssef Nada, a Brotherhood leader thought to be financing terrorism. It detailed a sophisticated plan to incrementally bring Sharia Law to the world, including deep political influence operations in the democratic institutions of the West. The Muslim Brotherhood has been diligently following this plan ever since.
The story of the infiltration of the Republican Party should start with Sami al-Arian, a former University of South Florida professor now convicted of being a leader of the Palestinian Islamic Jihad and admitted Muslim Brotherhood member. In 1997, his brother-in-law, Mazen al-Najjar, was held without bail based on classified evidence connecting him to terrorism after he appealed his deportation. Al-Arian began using his political connections to try to free his brother-in-law, arguing that his civil liberties were being violated. This effort ultimately failed, and al-Najjar was deported in 2002.
