Regan Prater, a man linked to white supremacist movements, pleaded guilty on Monday to the 2019 arson of the Highlander Research and Education Center (a historic social justice institution in New Market, Tennessee, where civil rights figures including Rosa Parks and Martin Luther King Jr. once trained) and to attempting to provide Hezbollah with identifying information on individuals allegedly affiliated with the Israeli government. The 2019 fire caused over $1.2 million in damage and destroyed decades of irreplaceable documents tied to the US civil rights movement; Prater was not arrested until April 2025, more than six years after the blaze. Sentencing is scheduled for 9 September in Knoxville, with prosecutors and defence having agreed that a term of no more than 20 years is appropriate.
