Oh come now. If Trump is in charge (as you say), then there should be no problem if he appoints Hillary as secretary of state. Trump is in charge and she will be following his policies. So what's the objection?
“then there should be no problem if he appoints Hillary as secretary of state”
I’m pretty sure Tillerson’s views are closer to Trump’s on most issues compared to Hillary. Trump has many appointees and no one person will be 100% perfect in matching his views. Things like gay boy scouts will not be on Tillerson’s agenda as secretary of state. I’m more interested in Tillerson and Trump being on the same page as far as Tillerson’s scope of work is concerned. Regarding that, there doesn’t seem to be any problems.
