Not to be stopped by a mere impeachment, Giuliani's tweets show he is still hard at work trying to sabotage the US election via Ukraine. And he is the president's personal lawyer, which says Trump is behind it.
Barr's efforts to further the Ukraine conspiracy blew up, for the moment at least. But it seems like he will keep trying to undermine democracy and the rule of law in the US.
So the whole cabal is still doing its dirty work.
