In 1968, Wilkins also served as chair of the U.S. delegation to the International Conference on Human Rights. After turning 70 in 1971, he faced increased calls to step down as NAACP chief. In 1976, he fell into a dispute with undisclosed board members at the NAACP national convention in Memphis, Tennessee. Although he had intended to retire that year, he decided to postpone it until 1977 because he thought that the pension plan offered to him by the NAACP was inadequate. Board member Emmitt Douglas of Louisiana demanded that Wilkins disclose the offenders and not impugn the board as a whole. Wilkins merely said that the offenders had "vilified" his reputation and questioned his health and integrity.
