First sitting US President to do so
Joe Biden became the first sitting US President to visit Greenwood, Tulsa, where hundreds of black Americans were massacred by a white mob in 1921.
100 years ago, the thriving Black community of Greenwood in Tulsa, Oklahoma was ruthlessly attacked by a white supremacist mob—as many as 300 Black Americans were killed and 10,000 were left homeless. Today, I’m visiting the Greenwood Cultural Center and meeting with survivors.

Leading a moment of silence alongside three survivors, he said it had been an "act of hate and domestic terrorism" and warned such behaviour still exists today.
Mr. Biden said it's remarkable no other president has been there:
