I could get behind your two. but I think both will hold more substantial posts. Press Secretary has to day in and out deal with the horde of presstitutes. I just see Ann as mean enough to make two or three of them cry every week. She got behind Trump early, and he rewards those loyal to him. I also do not see any other post she would fit. I see many potential posts for both Laura and Chris.
I would like to see Christie as U.S. Attorney General.
