A new investigation by the Associated Press revealed a number of Ku Klux Klan members are working inside the Florida Department of Corrections. The revelation came as part of an investigation into a failed KKK plot in 2015 to murder a Black man. The murder was planned as revenge for a fight in which a Black prisoner, Warren Williams, bit a white guard, Thomas Driver. The FBI was able to stop the plot, instead staging the murder, after an informant infiltrated the terror group. Tens of thousands of Americans are believed to belong to extremist white supremacist groups including the Klan. The FBI said such groups represent the greatest domestic terror threat.
