Trump is falling out with everyone in his inner circle mainly due to them not defending him enough or finding a way out of the quagmire he's got himself into. One of those is apparently one of his loudest and most deranged supporters, Rudy Giuliani.
From The Washington Post -
It says a lot about the grifter mindset and ego that every one of these ghouls saw trump and thought “ooh he’s so easily manipulated - I’ll use him as my meal ticket by debasing myself on the daily by agreeing with whatever he says, but there’s no way he’d ever betray
me as I am far too important!”
Giuliani, Michael Cohen, Spicer, Jeff sessions, Pence, Barr, the mooch, the list goes on.
Every one a craven careerist and yes-man, every one thrown under the bus the second they were no longer useful (and a new one scrambling to replace them). Strange old world.
