Before serving in Congress, Clay was active in the civil rights movement in St. Louis. He took part in protests against segregation and was elected to the St. Louis Board of Aldermen at just 28 years old.
In Washington, he became a strong advocate for civil rights, workers’ rights, and the Black community. He also helped found the Congressional Black Caucus and worked to support development and opportunity in St. Louis.
Leaders across Missouri remembered Clay as a trailblazer whose work helped shape American politics. His legacy continues through the rights, opportunities, and public service he fought for during his long career.
