15% of Terror Investigations Involve Refugees

Which is an even greater percentage of just immigrants

. . . Comey responded that out of 2,000-plus “violent extremist investigations … about 300 of them are people who came to the United States as refugees.” 

So 15 percent of the FBI’s terrorism cases are refugees – far more than their share of the immigrant population, let alone the general population. And that denominator of 2,000 presumably includes people with no immigration nexus at all – skinheads, antifa, Klan, environmental and animal rights extremists, et al. So the refugee share of immigration-related terrorism investigations is more than 15 percent, perhaps much more.
