Who dispersed protesters in the capital by ordering federal troops to fire on them with tear gas during the great depression?

During the Great Depression, President Herbert Hoover ordered federal troops to disperse protesters in Washington, D.C., specifically the Bonus Army, which consisted of World War I veterans demanding early payment of their bonuses. The troops, led by General Douglas MacArthur, used tear gas and other means to clear the encampment in July 1932. The violent eviction drew widespread public criticism and negatively affected Hoover's reputation.
