It will be easier for Trump to replace Sessions after Jan 3, 2019 if the GOP gains Senate seats this November. AG nominations requires Senate confirmation.
My guess too. If gop picks up 3-5 seats sessions is gone by January. Trump is just waiting to see if he has a little more cushion than he has now. But sesssions is on the chopping block, no doubt about it.
At least John McCain won’t be blocking his nominees.
