Eleanor was an advocate for civil rights. She believed in equality. This was evidenced when she organized a concert for African American contralto Marian Anderson on the steps of the Lincoln Memorial after she was denied permission to sing in Constitution Hall by the Daughters of the American Revolution. In relation to this event, Eleanor also wrote a curt letter to the organization to inform them of her resignation. In later years, she became so outspoken that the Ku Klux Klan put a bounty of $25,000 on her head. She also only offered John F. Kennedy her endorsement during his presidential campaign under the condition that he would vocally support equal rights for African Americans.
