Dude, this NXIVM #CultOfKeith stuff is defo the motherload fam.
Mike Huckabee is close to this group to the point where he's even got called out for it in the news.
I think it's definitely possible Sarah Huckabee Sanders was chosen for her connection to Mike as much as her talent, just like Betsy DeVos was chosen as Education Secretary because it allowed easy access to her brother Erik Prince of Blackwater.
Many of Trump's "1st Phase" choices have been this type I believe. It was so important for Trump to be able to negotiate with the bad guys. This is why McMaster was called out for meeting with Petraeus and Soros, well uh, yeah, someone has to meet with these guys. I would also say Rex Tillerson was another one of these guys. He has had some important ties to Russians, and clearly now he's not needed. Even Bannon seemed to have a close relationship with Kissinger.
Further bolstering the "Sarah Huckabee Sanders" thing seems to be the celebs strange hate of her. Jim Carey who seems scared out of his mind, chose HER to mock. Not Trump, not Pence, not Sessions or Bannon.
Sarah.
