Outgoing New Jersey Gov. Chris Christie is still steamed about getting dumped as head of President Trump’s transition team — and insists that the commander-in-chief’s first year would have been far less rocky had Christie been on the job.

“I can only tell you who ultimately executed on it and that was [Steve] Bannon, [Reince] Priebus and [Jared] Kushner,” Christie told NJ.com on Monday. “They were the three guys in charge and they were the ones who ultimately made that recommendation to the president. And I think they ill-served him by doing it.”

He added, “I think 75 percent of the problems that they had at the beginning of the administration could have been avoided if they had followed the transition plan ­[I devised].”
