Reminds me of a scene from a West Wing episode in which the lesson is that good press control means not over-reacting to small points like this.

(One of my favourite scenes for their acting, though I can't find a video.)

  Yes, I hired the guy, but that's not... Legitimate news organizations are going to cover 
  this to say nothing of the people who hate us who are going to run it over, over, over, 
  over, over...This guy was here for three minutes and he was fired. He is not credible. 
  I'm a lawyer, I'm telling you. That has to be made clear. Every time he makes a factual 
  mistake we got to come out with a press release. Every time he misquotes or misidentifies 
  anyone we need to have an affidavit swearing to the truth. If there's a comma in the 
  wrong place he needs to be killed until he is dead and he needs to be killed again or 
  he is going to keep biting at our ankles and I mean all through the campaign. He needs 
  to be a joke, or we're going to be.

  [snapping fingers rhythmically] Boy, boy, crazy boy. Keep cool, boy...

  I'm not screwing around. 
  
  C.J.
  Me neither. Sit down.

  I'm not going to be a victim of this. 
  
  C.J.
  Let me tell you something I've learned in my years. There are victims of fires. There 
  are victims of car accidents. This kind of thing, there are no victims--just volunteers. 
  Of course we'll get in the game. I'll talk to the editors of the major papers but we're 
  not going to publicly refute every bogus charge. First of all, there are too many of them. 
  Second of all, I'm not going to give this guy and his book the weight of the White House. 
  As far as the press is concerned I've read the book because I had to. You have a vague 
  recollection of the guy but he wasn't here long enough to make a lasting impression. 
  Have you read the book? Of course not. You're too busy doing a job.

At the end of the day, nit-picking down to this level just makes you seem desperate to discredit, regardless of how true (or otherwise) your main arguments might be.
