Call it family values, Christian values, personal integrity or whatever you like. I consider myself to lucky to have be taught that when one is wrong one should admit it as opposed to lying in an attempt to cover it up. Then the correct course is to apologize to those who were wronged. Not taking step two is what most people would call a half hearted or disingenuous apology. Do this and things always go better for both parties involved and there is some closure.
Mr. Trump seems to have never learned these two basic things. He is surrounded by yes men and women who fear him enough to never be critical and never say a mistake might have been made or an apology might be warranted. I suppose you can run a business empire that way and fire those who do not agree with you but this is where business and politics differ. Politicians, being elected to pubic not private office, need to act differently. I doubt Trump will ever learn what most people already know. A habitual offender. Next case...
