"To carry out these twin goals of fanning racial flames and exacting revenge, Roof further decided to seek out and murder African Americans because of their race," Lynch said.
Lynch said prosecutors haven't decided if they'll seek the death penalty.
South Carolina will also be charging Roof in the incident. The hate crime charges had to come from the federal level because the state doesn't have hate crime laws.
