The next day, Charles Edward Russell, a co-founder of the National Association for the Advancement of Colored People (NAACP) and chair of the DC citywide Inter-Racial Committee, held a meeting of the Marian Anderson Citizens Committee (MACC). This included the National Negro Congress, the Brotherhood of Sleeping Car Porters, the American Federation of Labor, and the Washington Industrial Council-CIO, plus church leaders and activists in the city and numerous other organizations. MACC elected Charles Hamilton Houston as its chairman and on February 20, the group picketed the Board of Education, collected signatures on petitions, and planned a mass protest at the next board meeting.
