After William Barr dealt dismissively with the claims of Trump that the voting machines were fraudulent and he realized that Trump would not change his mind no matter how often Barr told him there was no supporting evidence or information of fraud, Barr put it this way when he gave evidence to the House of Representatives Select Committee,
I was somewhat demoralized because if he really believes this stuff he has lost contact with, he has become detached from reality. On the other hand when I told him how crazy some of these allegation were, there was never any indication of interest in what the actual facts were.”
This is precisely the point. Trump actually had no interest in the truth. None at all. He was only interested in what reinforced his narrative that the election was stolen. Absolutely nothing else mattered.
Trump’s daughter, Ivanka Trump when confronted with what Barr had said, told the Capitol investigation this: “It affected my perspective. I respected Attorney General Barr. So, I accepted what he said was said.” Another long-standing loyal Trump supporter admitted that her father was wrong about a stolen election.
As Liz Cheney along time Trump supporter explained
“After Barr’s resignation on December 23rd the acting Attorney General who replaced him Jeff Rosen and the acting Deputy Attorney General Richard Donoghue told President Trump over and over again that the evidence did not support allegations he was making in public.”
And of course, Trump continued his insinuations no matter how many of his own advisors advised him that he was wrong for there was no significant fraud in the election. None of them found fraud even though they knew their boss wanted to find fraud. The new attorney general also told Trump that the evidence did not support the statements he was making in public.
None of this mattered to Trump. He just did not care about the truth or reality. Should a man like this be trusted with being in charge of the armed forces, or the nuclear buttons, or anything for that matter?
