Tariq Ramadan, a Swiss-born professor at Oxford University, is "one of the most important and relevant voices for Western Muslims," said Ahmed Rehab, executive director of the Council on American-Islamic Relations in Chicago. Ramadan is the keynote speaker for CAIR-Chicago's annual banquet. About 1,500 people are expected to attend the event at the Drury Lane Banquet Hall. This year's theme is "Unapologetic Activism: Our Legacy, Our Promise."
