Protesters rally at the White House against the death in Minneapolis police custody of George Floyd, in Washington, D.C., U.S. May 31, 2020. Jonathan Ernst: "On this night, protesters who had gathered near the White House in response to the police killing of George Floyd in Minneapolis were met by riot police firing tear gas and rubber ordnance. Protesters will frequently use the White House as a backdrop for their cause, but this was the first time I'd seen it quite like this – with maybe the world's most recognizable facade looming behind a cloud of smoke and the silhouetted figures of protesters dodging ... projectiles."
