In August 2008, Black's 19-year-old son Derek Black was elected to one of 111 seats on the Palm Beach County, Florida, Republican committee, with 167 of 287 votes. The committee however, refused to seat Black, citing a loyalty oath he failed to sign before registering his candidacy. The oath states candidates must refrain from activities "likely to injure the name of the Republican Party." He hosted the "Derek Black Show" weekdays on a local West Palm Beach, Florida, AM radio station, WPBR, to which Don Black paid $600 a week to broadcast content on. The radio show ended in January 2013, with Derek Black appearing on few episodes over the last year.
