I thought it was BJ Clinton who was rumored to have fathered a black child.
The 2008 election scandal was that McCain had an affair with a lobbyist. The media covered that rumor while they defended not covering John Edward’s bastard love child.
Karl Rove said Monday that he had nothing to do with a whisper campaign during the 2000 Republican presidential primary claiming Sen. John McCain (R-Ariz.) had an illegitimate black child.
Rove, who was working for then-Gov. George W. Bush, said during an interview on NBCs Today Show that the rumor came from a professor at Bob Jones University and not the Bush campaign.
