Extremism is definitely not all Islam, but there are certain groups in Islam...Wahabism and, to a lesser extent, the Muslim Brotherhood. They are definitely terrorist groups and they are hate groups. They should be stopped. We're getting a lot of monetary support from Saudi Arabia to open up mosques over here, and they're sending their own clerics over here, who are teaching Wahabi Islam to young kids They're enticing them into getting into terrorism, whether here or overseas. Obviously many of them are travelling overseas, but there were two incidents that happened over here. So this has to be stopped.
