Dan Rather – in what was supposed to be the defining moment of his CBS career, Rather compiled a report which the left hoped would take down then President George W. Bush prior to the 2004 elections. Instead, the documents Rather used to “prove” Bush’s Texas Air Guard service had been less then stellar were actually forgeries. Instead of admitting his error, Rather doubled down on the report and was subsequently released from CBS News a year earlier than his contract intended.
I think you are a little confused. the memos were forgeries, but the evidence that Bush got preferential treatment in getting into the National Guard and that he shirked his duty before his enlistment were up were there.
Not that I think this was a big deal... the fact is, when Vietnam was winding down. the National Guard was in chaos as all the guys who signed up to get out of the draft left and were replaced by guys who actually wanted to be there.
