In his appearance before the committee, Comey broadened this claim to include President George W. Bush, under whom he served as Deputy Attorney General. The reason, he - From Power Line
When I was deputy attorney general, I had one one-on-one meeting with President Bush about a very important and difficult national security matter.
As Deputy Attorney General, he refused to sign the reauthorization order on behalf of DOJ, and he was one of those who rushed to John Ashcroft’s hospital bedside.
As the participants started to leave the Oval Office, the Attorney General lingered by my chair, but the President thanked him and said he wanted to speak only with me.
The email was substantive: it documented Comey’s account of the conversation he had with the president.
He did document his story about his meeting with President Bush, in great detail, in a “report” that was turned into “unclassified notes.” James Comey says there is a pattern to his dealings with presidents: he is an honest man who only needed to create memos to document his conversations with Donald Trump, because Trump is untruthful.
