Trump supporter has been arrested making racially-motivated threats against students at the historically-black Howard University in Washington, DC.

The 26-year-old John Edgar Rust, who was convicted in 2012 of “indecent liberties with a child by custodian and aggravated sexual battery,” made threats against the lives of Howard students on the infamous 4chan message boards in 2015.

Rust made his post during a period of racial unrest at Missouri University.

“I left MU yesterday because I couldn’t put up with it anymore,” Rust wrote in his Facebook post. “I go home to Maryland and what do I see? The same old s***. Turn on the news and it’s always the n***** causing trouble everywhere. So I’ve decided. Any n***** left at Howard University after 10 tomorrow will be the first to go. And any of those cheapskate n***** who try to get out using the metro will regret that choice real fast.”

Rust also claimed that “it’s not murder if they’re black.”

Because he made the post from a Panera Bread in Alexandria, Virginia, Rust was charged with “transmission in interstate commerce of a communication containing threats to injure the person of another” due to the location of Howard. He could be sentenced to up to five years in prison.
