The radicalization of Americans by Islamic State and other groups, particularly through sophisticated use of social media, is a top concern for the FBI as it grapples with evolving terrorism threats, Director James Comey said on Thursday.
Like other militant groups, Islamic State, also known as ISIL, has called for lone wolf attacks in Western countries and has specifically encouraged attacks on soldiers, law enforcement officers and the intelligence community, Comey said at an appropriations subcommittee budget hearing.
Comey referred to the group's efforts to recruit Americans to join Islamic State fighting in Syria and Iraq, then have them return to the United States to commit acts of terrorism.
"ISIL's widespread reach through the Internet and social media is most concerning as the group has proven dangerously competent at employing such tools for its nefarious strategy," Comey told the panel as he presented his $8.48 billion budget request for fiscal year 2016.
