But what is notable, besides the president’s factual errors, is that he cited Comey as a credible source. Though he had previously wanted the memos discounted, Trump suddenly reversed and wanted the documents seen as authoritative.
The reason for the change is obvious: When Trump expected the memos to be all bad for him, they were “phony.” And when he saw the memos as an opportunity to profess his innocence, they were reliable. As he often does, Trump measured truth by a single standard: favorability.
Trump has called Comey a liar yet also has reveled in Comey’s remarks about former attorney general Loretta E. Lynch and former FBI deputy director Andrew McCabe, gleefully tweeting that Comey threw both “under the bus.”
Trump seems happy to accept Comey’s criticism, in the new book “A Higher Loyalty,” of Lynch’s “tortured half-out, half-in approach” to the Hillary Clinton email investigation. And Trump appeared to enjoy Comey’s Thursday interview on CNN — or at least the part in which Comey responded to news of a criminal referral against McCabe.
“That’s part of accountability,” Comey said, “an examination of what the consequences should be if there was material lying.”
Comey throws AG Lynch “under the bus!” Why can’t we all find out what happened on the tarmac in the back of the plane with Wild Bill and Lynch? Was she promised a Supreme Court seat, or AG, in order to lay off Hillary. No golf and grandkids talk (give us all a break)!— Donald J. Trump (@realDonaldTrump) April 15, 2018
James Comey just threw Andrew McCabe “under the bus.” Inspector General’s Report on McCabe is a disaster for both of them! Getting a little (lot) of their own medicine?— Donald J. Trump (@realDonaldTrump) April 19, 2018
Judging a person’s credibility is not an all-or-nothing proposition. Comey could, in theory, tell the truth about some things and lie about others.
But Trump's selection of what to believe and disbelieve appears to be purely self-serving, rather than evidence-based. When Comey writes or says something that Trump likes, the president credulously spreads it to his 51 million Twitter followers. And when Comey writes or says something Trump dislikes, the president calls the former top cop an “untruthful slime ball.”
