Former Homeland Security Secretary Jeh Johnson on Sunday said that Confederate monuments are becoming “symbols and rallying points for white nationalism,” neo-Nazis and the KKK.

“We fought a world war against Nazism. The KKK rained terror on African Americans for generations,” Johnson said. “And so a number of Americans rightly, Republican and Democrat, are very concerned and very alarmed, and I salute those in cities and states who are taking down a lot of these monuments for reasons of public safety and security.”
