FBI Director Christopher Wray said that the bureau has made about 100 arrests of domestic terrorism since October and that the majority of them were tied to white supremacy.

“I will say that a majority of the domestic terrorism cases that we’ve investigated are motivated by some version of what you might call white supremacist violence, but it does include other things as well,” Wray said, speaking at the Senate Judiciary Committee hearing on FBI oversight on Tuesday.

Senator Dick Durbin (D-IL) asked Wray to quantify the threat of domestic terrorism.

“In terms of number of arrests, we have, through the third quarter of this fiscal year, had about, give or take, a hundred arrests in the international terrorism side, which includes the homegrown violent extremism,” Wray responded, clarifying that those numbers were for this year.  “But we’ve also had just about the same number, again don’t quote me the exact digit, on the domestic terrorism side, and I will say that a majority of the domestic terrorism cases that we’ve investigated are motivated by some version of white, what you might call white supremacist violence, but it includes other things as well.”
