I don’t see any advantage in have Christie in the WH, either. He is a total suckup to Trump. (Watch his body language on election night, totally obsequious.)
I never trust a suckup. They are opportunists and will turn on you as soon as a better opportunity comes along. Plus, they only say what you want to hear. I don’t need an echo.
I don't know why they all ignore the fact that he has put SHARIA loving Muslims on the bench, in Jersey, as judges, that taxes there are high, and that he has NOT been a "good" governor at all.
Christie and Trump and their wives have been good friends for 15 years. Normal life for them to see each other once in a while when the opportunity presents itself.
Presidents have friends too. Trump has more than most.
