FBI Director Christopher Wray said Thursday that white supremacy presents a persistent" and "pervasive" threat to the United States. Wray also spoke out against hate crimes and was asked by Democrats what the FBI was doing to crack down on hate crimes, which they say have ticked up during Trump's presidency. "We are determined not to tolerate hate-filled violence in our communities, so we're going to aggressively investigate those cases," Wray said, adding that there has been an increase in "the reporting of hate crimes," but that this doesn't automatically mean more hate crimes were happening. FBI efforts to encourage the public to report hate crimes could be yielding benefits, he said. These comments aren't exactly in line with what Trump has said about the topic of white nationalism. Trump, who appointed Wray in 2017, has downplayed the danger of white nationalism and even praised some of the Nazi sympathizers who marched in Charlottesville, Virginia. After the New Zealand mosque massacre last month, where a right-wing extremist killed 50 Muslim worshippers, Trump said he didn't consider white nationalism to be a rising global threat. "I think it's a small group of people that have very, very serious problems, I guess," Trump said. An FBI assessment released last year found that there was a 17% spike in reports of hate crime incidents in 2017, compared to 2016.
