I think another factor was from what happened on Election Night. As the Trump family and entourage were on the stage for his victory speech, Chris Christie was practically shoving people out of his way to get closer to Trump so that he could get into the same camera shots with him.
The Star-Ledger/NJ.com is so liberal. It’s like the NY Times.
Re: Christie falling out of favor, I think Trump also didn’t like the quality / talent of people Christie was recommending as part of transition efforts, as well as the incessant politicking......
I see now that Christie not a lock for GOP chair.
