By the early 1920s, Esposito earned another nickname, Diamond Joe, due to his frequent wearing of diamond cufflinks, diamond rings, and other jewelry. Esposito had become a Republicanward boss of the Nineteenth Ward in Chicago. He was one of the earliest Italian Americans elected as aldermen.[4] Esposito provided political protection to the bootlegging gangs of Chicago's Italian communities, including the South Side gang of mob boss Johnny Torrio and the Genna brothers. In May 1921, Esposito famously attended the funeral of his political protégé Antonio D'Andrea. Several years later, Esposito also attended the funeral of another criminal ally, Angelo Genna murdered on May 25, 1925.[4]
Rivalry with Al Capone and death
After Torrio retired, Esposito was a rival of his old gang, now led by Al Capone and known as the Chicago Outfit, and on March 21, 1928, Esposito was attacked and killed in a drive-by shooting on his front steps, with his two nieces right inside the house.
