(U//FOUO) This product is one of a series of intelligence assessments published by the

Extremism and Radicalization Branch to facilitate a greater understanding of the

phenomenon of violent radicalization in the United States. The information is

provided to federal, state, local, and tribal counterterrorism and law enforcement

officials so they may effectively deter, prevent, preempt, or respond to terrorist attacks

against the United States. Federal efforts to influence domestic public opinion must be

conducted in an overt and transparent manner, clearly identifying United States

Government sponsorship.
