A Northern Virginia think-tank is suspected of being a pivotal cog in the Muslim Brotherhood's high command in America, newly released federal law enforcement records indicate.

The Investigative Project on Terrorism obtained 596 pages of records from a closed FBI investigation through a Freedom of Information Act request. Dozens of the pages released are redacted. But other sections show that International Institute of Islamic Thought (IIIT) board members Jamal Barzinji and Yaqub Mirza are listed among 'members and leaders of the IKHWAN.' Barzinji was identified as the secretary general for the Islamic Society of North America (ISNA) at that time. The Ikhwan is an Arabic reference to the Muslim Brotherhood.
