The Brotherhood of Sleeping Car Porters, led by A. Philip Randolph, played a pivotal role in President Roosevelt's order to prohibit discrimination in the government and defense industry.
Randolph threatened to march on Washington with 100,000 protestors to fight race discrimination in war industries, prompting Roosevelt to sign Executive Order 8802. This order banned racial discrimination in defense industries and established the Fair Employment Practice Committee to monitor hiring practices.
