Who was a civil rights activist who put pressure on president roosevelt regarding defense jobs?

The appropriate response is Asa Philip Randolph. He was a pioneer in the Civil Rights Movement, the American work development, and communist political gatherings. 
He sorted out and drove the Brotherhood of Sleeping Car Porters, the principal transcendently African-American guild. In the early Civil Rights Movement and the Labor Movement, Randolph was a voice that would not be hushed. His consistent disturbance with the help of kindred work rights activists against uncalled for work hones in connection to non-white individuals, in the long run, drove President Franklin D. Roosevelt to issue Executive Order 8802 out of 1941, forbidding separation in the protection enterprises amid World War II. The gathering at that point effectively compelled President Harry S. Truman to issue Executive Order 9981 out of 1948, finishing isolation in the outfitted administrations.
