He opens with the suggestion that his debate was being taken out of context by various media outlets and promoting ideas he doesn't really believe, and then cops to the fact he choked under the pressure of a public debate and didn't express himself very well. He then attempted to express himself much better, thanks to having a prepared statement ready to go, and read from it, essentially backing up all the ignorant beliefs at the core of every single dumb utterance that fell from his fucking head during the debate. There is no real apology, and the only regret he seems to have is for his own lack of preparation. He apparently believes if he'd prepared more, nobody would be mad at him.
So it's a "Sorry not sorry. Don't trust what the media says about me."
