The House Judiciary Committee will look into rising rates of hate crimes and white nationalism in the U.S. at a hearing on Tuesday, April 9.

After the midterm elections last year, Rep. Jerrold Nadler, the chairman of the committee who was then the ranking member, promised to hold hearings in the new Congress on the rise of racially and religiously motivated violence.

The committee will “examine the causes of racial and religious violence, assess the adequacy of federal hate crimes statutes, and scrutinize targeted domestic surveillance of specific groups,” Nadler wrote in a letter last November to the Homeland Security Department, Justice Department and FBI.

The number of incidents involving hate crimes increased for a third straight year in 2017, according to FBI data released In November. Hate crime incidents rose by 17 percent in 2017 compared to 2016. From 2015 to 2016, the FBI reported a 5 percent increase.
