FBI NAIT Investigation
Around 1987-88, FBI agents in Indianapolis began investigating the North American Islamic Trust (NAIT) and the Islamic Society of North America (ISNA). The investigation found that NAIT, which holds title to dozens of mosques throughout the country, and ISNA are Muslim Brotherhood front groups. NAIT grew out of the Muslim Students Association (MSA) and remains affiliated with the Islamic Society of North America (ISNA), investigation records alleged. The records also showed that International Institute of Islamic Thought (IIIT) board members Jamal Barzinji and Yaqub Mirza are listed among "members and leaders of the IKHWAN [or the Muslim Brotherhood]." According to an FBI memo, a source whose name is redacted in the investigative file "advised that the IIIT, NAIT (North American Islamic Trust) and all the subsidiary and sponsoring Muslim organizations under the control of the IIIT and the SAAR Foundation are in fact IKHWAN organizations."
