George W Bush had a falling-out with Dick Cheney over Mr Bush's refusal to pardon the vice-president's top aide in a spy-outing scandal, Mr Bush has said.
Libby was convicted of perjury and obstruction in a probe into the leaking of CIA spy Valerie Plame's identity.
Mr Bush told NBC News his decision at the end of his presidency merely to spare Libby a prison sentence rather than pardon him angered Mr Cheney.
But, in a interview to promote a book, he said the friendship had recovered.
"We are friends today," Mr Bush said. "I was a little concerned at the time. It was a hard decision at the time but that's what you do when you're president, you make hard decisions."
