America’s intelligence officials need to do more to combat violent extremism from the Christian and Jewish communities, a House Democrat said on Thursday, one day before the anniversary of Sept. 11.

Andre Carson, D-Ind., told FBI Director James Comey to do more to educate the public on that topic. “I do want to say … director, respectfully … When we talk about radicalization, Islam does not have a monopoly on radicalization or even cult-like activity. There are so-called Christian groups that are purporting racial mythologies that are just as destructive in the Midwest.”
