Since its onset, the Program on Extremism has devoted substantial attention to the activities of Islamist groups, particularly in Western countries. The Program’s director, Lorenzo Vidino, has studied the activities of the Muslim Brotherhood in Europe and North America for more than 20 years, authoring two acclaimed books and regularly consulting with various governments on the subject. The Program has also produced reports on the Salafist movement in America and other Islamist movements.
