There are “inaccuracies” in the ads? What are they? The article does not elaborate or even explain them. Nor does Newt.
It's been a while since I saw the ads, but the one thing that I remember that struck me as inaccurate was a claim that Newt supports amnesty for 11 million illegals. I think that is a gross exaggeration of his position and don't blame him for taking exception to it.
Newt has made clear through his lawyers letter to tv stations that he considers the claim he was fined $300,000 for ethics violations to be false. Newt claims he was not fined, but was asked to reimburse for the cost of the investigations. His basis for this is lost on me, the sanction was clearly reported as a fine when it happened and as I recall Newt did admit wrongdoing and apologize.
