Why should Trump regret anything? Voters didn't care and the Republicans he ridiculed let it slide. =>https://twitter.com/learyreports/status/1054475586603835392 …
Trump is being honest. If he expressed what appeared to be sincere regret it might work, but only if he stopped behaving this way, which clearly he won't. My point is you can't blame him in terms of the politics. I'm not making a moral judgment here either way.
