When we posted a FactCheck Wire item last week about a dispute between White House Press Secretary Robert Gibbs and longtime correspondent Helen Thomas, we were surprised that Gibbs didn’t know President Obama had taught constitutional law at the University of Chicago’s law school. That’s a fact that had come up many times during the campaign, after all, including during a kerfuffle about whether Obama had the right to call himself a "professor."
Well, sometimes you have to walk a story back so far it falls off a cliff.
