Tablighi Jamaat
The U.S. Government has closely monitored Tablighi Jamaat since September 2001. According to US officials, though the Tablighis do not have a direct link with terrorism, the teachings and beliefs of Tablighi Jamat have been a cornerstone for joining in radical Muslim groups. Rizwan Farook, one of the perpetrators of the 2015 San Bernardino attack, was a student of the teachings of Tablighi Jamaat. Tablighi Jamaat leaders have denied any links with terrorism. The Tablighi Jamaat generally avoids political activities and debates, and instead focuses on religion only. The Jamaat does admit that it attracts all sorts of individuals and doesn't control its membership.
