FBI Director James Comey says recruitment of potential homegrown terrorists by Islamic State extremists is a widespread threat that goes on "24 hours day" across the United States.
Comey says hundreds of people are "consuming" social media efforts to either draw them overseas to join the extremists, or stay and kill at home. He says there are ongoing investigations in all 50 states as the FBI tries to identify and stop those most likely to act.
Comey talked with reporters Wednesday during a visit to the FBI field office in the Cincinnati area. Its Ohio region had two arrests this year of young men charged with plotting terrorist acts to support Islamic State extremists.
He says another top concern is rising violent crime in many U.S. cities, including Cincinnati.
