Fox News reports that “Homeland Security Secretary Jeh Johnson said Sunday, on the 15th anniversary of the Sept. 11 terror attacks, that the country is now safer against another such large-scale terror attack but acknowledged being ‘challenged’ by lone radical Islamic terrorists — with active FBI cases in all 50 states.”

“’Our government’s become pretty good at detecting and preventing something hatched from overseas,’ Johnson told ‘Fox News Sunday’ from the World Trade Center memorial in New York City. ‘We’re better than we were 15 years ago. Where we’re challenged, however, is the lone wolf-style attack.’”
