In 1921, Black defended E. R. Stephenson in the sensationalistic trial for the murder of Fr. James E. Coyle. He joined the Ku Klux Klan shortly after, thinking it necessary for his political career. Running for the Senate as the “people’s” candidate, Black believed he needed the votes of Klan members. Black would near the end of his life admit that joining the Klan was a mistake, but said “I would have joined any group if it helped get me votes.”[9]

Adds new meaning to “Black Byrd singing in the “dead of night.”
Black’s anti-Catholicism was personal. However, the Klan was a good fit for him, because the Klan was far more worried about Catholic and Jewish influence than about the blacks.
