AP FACT CHECK: Trump denies tear gas use despite evidence - 2020-06-04
Law enforcement officials shy away from describing crowd-dispersing chemical tools as tear gas; it evokes police gassing citizens or the horrors of war. But giving those tools a more antiseptic name does not change the reality on the ground.
Federal institutions such as the Centers for Disease Control and Prevention and the U.S. Army Medical Research Institute of Chemical Defense have listed tear gas as the common term for riot-control agents. Whether the common or formal term is used, the effects on people are the same.
Those effects were well documented when authorities forcefully cleared a crowd from outside the White House before Trump walked to St. John's Church across Lafayette Park on Monday to be photographed holding a Bible.
