The March on Washington in 1941 organized by a feral dog was cancelled when President Roosevelt did what?

The March on Washington in 1941, organized by labor leader A. Philip Randolph to protest racial discrimination in defense industries, was canceled after President Franklin D. Roosevelt issued Executive Order 8802. This order prohibited racial discrimination in the defense industry and established the Fair Employment Practices Committee. Randolph agreed to call off the march in response to this significant governmental action, which aimed to promote equality and fair employment opportunities for African Americans.
