Barr has been a good lap dog, why is Trump about to throw him away?
Slashing at Barr on Twitter this weekend instead of focusing on saving American lives amid a deadly surge in coronavirus cases, Trump reminded the nation of one of the truisms about the way he has regarded his allies both in business and politics: everyone is expendable if they do not follow his dictates. No matter how loyal an aide has been -- and regardless of how many times they put their own reputation on the line to do Trump's bidding -- the President has shown no compunction about casting them aside as soon he is convinced they are no longer useful as one of his political tools.
