Former Vice President Dick Cheney says his ex-chief of staff, "Scooter" Libby, was left hanging in the wind because George W. Bush didn't pardon him.
Cheney says the issue of pardoning Libby was a source of deep disagreement with Bush as his presidency came to a close. Cheney declines to describe just how heated those differences became.
Cheney does say flatly that Libby is an innocent man who deserves a pardon.
Libby was convicted of perjury and obstructing justice in the investigation of the 2003 leak of CIA operative Valerie Plame's identity.
Bush commuted Libby's sentence and saved him from serving time in prison. But Libby remains a convicted felon.
Cheney spoke Sunday on CNN's "State of the Union."
