President Barack Obama remembered civil rights leader Percy Sutton who died Sunday at the age of 89.

Sutton first made his name as civil rights leader Malcom X's attorney. Sutton then went on to become a millionaire media mogul and later became Manhattan's longest-serving borough president. He was the first serious black candidate for New York City mayor in 1977.

"Percy Sutton was a true hero to African Americans in New York City and around the country," Obama said. "His life-long dedication to the fight for civil rights and his career as an entrepreneur and public servant made the rise of countless young African Americans possible."

During World War II, Sutton also served with the Tuskegee airmen, the well-known all black unit of fighter pilots. The cause of Sutton's death is still unknown.
