Conservative talk radio giant Rush Limbaugh suggested Friday that the U.S. may be “on the cusp of a second civil war” as the country contends with new racial tensions following the violence in Charlottesville, Va. last weekend.

“America is under attack from within,” Limbaugh told his listeners, according to a transcript. He warned that now, more than ever in his life, is “our culture, our history, our founding” under assault.
