In the aftermath of an Ohio man being charged with killing a woman in Charlottesville, Virginia, this month, Sen. Sherrod Brown asked the FBI on Tuesday to provide information the bureau has on “domestic terrorist organizations or hate groups” operating in Ohio.

In a letter to FBI Director Christopher Wray, Brown, D-Ohio, wrote that “the presence of domestic terror organizations and hate groups in Ohio” poses a “threat to both public safety and national security. And I firmly believe that every Ohioan, and every American, has a right to know whether domestic terror organizations or hate groups are known or suspected by law enforcement to have a presence in their community.”
