-- Siraj Wahhaj - a character witness for convicted 1993 World Trade Center terrorist "blind sheik" Omar Rahman, and a man who reportedly called for replacing the American government with a caliphate.  According to Siraj Wahhaj, "if only Muslims were clever politically, they could take over the United States and replace its constitutional govt. with a caliphate. If we were united and strong, he said, we would elect our own emir and give allegiance to him. Take my word if 8 million Muslims unite in America, the country will come to us."
