Former FBI counter-terrorism Special Agent John Guandolo says the “vast majority” of the 2,200 Islamic organizations, centers, and mosques in the United States are a part of a broader “Jihadi network” intent on imposing Sharia Law in America.

Guandolo Breitbart News the San Bernardino terrorist, the UC Merced stabber, the Chattanooga shooter, and the Boston Bombers can all be traced back to such Islamic Centers where “they were supported and trained.”

Guandolo said that the San Bernardino terrorists attended the Islamic Center of Riverside, which he said was a “a Muslim Brotherhood Center.” He noted that the Boston Bombers attended the Islamic Society of Boston, which he said was a subsidiary of the Islamic Society of North America that was founded by an al-Qaeda guy who used to advise former President Bill Clinton and former Vice President Al Gore and is now in prison.

He said there are over 2,200 Islamic Centers and mosques in America and the “vast majority of them are a part of this network — they’re hostile.”
