Report: Homegrown Extremism Threat Still Growing

Homegrown extremism continued to grow over the past three months, according to a report from the House Homeland Security Committee.

"Cases of homegrown Islamist extremism in the U.S. continue rise as U.S. Persons radicalize," the report reads. "Since the September 11 attacks, there have been 214 homegrown jihadist arrests in the United States, of which 136 were ISIS-related."

It adds, "ISIS' campaign to encourage and guide terrorist attacks in the West continues. So far in 2017, there have been 14 homegrown jihadi cases in America and the FBI continues to investigate cases in all 50 states."

Rep. Mike McCaul, R-Texas, told The Washington Free Beacon that the terrorist group's defeat in Mosul last month was a "significant blow" against ISIS, but that they may step up their attacks against the West in response.

"While the American-backed liberation of Mosul is a major victory, the fight is far from over," he said in a statement. "As ISIS continues to experience battlefield losses in Iraq and Syria, we must stay vigilant in order to keep them from establishing new safe havens and stop them from returning to the West."

A U.S. Army soldier, Sgt. Ikaika Kang, was arrested last month on multiple charges, including an attempt to "provide material support and operational expertise as an air traffic controller to ISIS," and later planned to "kill a bunch of people," according to the committee's report.
