The couple, through the The Clooney Foundation for Justice, have made a $1 million donation to the Southern Poverty Law Center (SPLC) that will fund a joint initiative to combat hate groups.
The move comes more than a week after an August 12 "Unite the Right" rally sparked violence in Charlottesville, Va., that left one woman dead and 19 injured. Two Virginia state troopers who were monitoring the protests were also killed in a helicopter crash.
In a joint statement issued Monday via the SPLC, the couple said they were "proud" to support the organization "in its efforts to prevent violent extremism in the U.S."
"What happened in Charlottesville and what is happening in communities across our country demands our collective engagement to stand up to hate," they said.
