Hmm, do you suppose he could be pumping his soon-to-be-released book? Nahhh, that would be cynical thinking, wouldn't it?
Whenever anyone opens his mouth to the media and a bunch of controversial and/or critical statements about a current administration tumble out, I look to see if he has an upcoming book release. Remarkably, in nearly every case it appears that they just coincidentally stand to fill their pockets if they can stir up interest in their rhetoric.
Not that it matters; people who want to believe will gladly overlook obvious ulterior motives in order to get their own biases validated.
