Not only did he fire every one in every state, I believe it was done day one of his administration!
Please correct me if the date is incorrect, someone.
This action was done partly to cover-up what was pending in Arkansas over Whitewater misdeeds but other wrong doings in other states, and it worked!!!
Unfortunately, for President Trump, having no knowledge whatsoever of the workings in every aspect of the job, went about the important items he had promised the American voters but left in place people sworn to keep him from doing the job he was hired to do and many are still in place doing just that!
Worst of all, we have jokers in Congress (Senate too) who rush to the microphones to talk tough (Linda Graham comes to mind) but first and foremost are ardent Swamp dwellers and never Trumpers, who continue to cooperate with liberals rather than those home folks they swore to represent and to saw to it that the GOP lost in 2018 (thanks to Paul Ryan and others sitting out that election.
Unfortunately, Trump didn't have much to choose from. Normals have been chased from all facets of Government, they have other options, and simply choose not to get involved in the pigsty that is modern-day government.
