Protesters Demonstrate Against Police Killing of George Floyd

U.S. Park Police stand guard in front of the White House during a demonstration against the Minnesota police killing of George Floyd, on Tuesday, June 2, 2020 in Washington D.C. Activists nationwide defied curfews in some of the larger cities late Monday and early Tuesday, just hours after President Donald Trump threatened to send the U.S. military into cities that don't control the violent demonstrations.
