Sen. John McCain (R-Ariz.) paid tribute Monday to Col. George "Bud" Day, one of the nation's most highly decorated military veterans, who died Saturday after a long illness. Day spent 5½ years as a POW in Vietnam and shared a prison cell for a time with McCain at the infamous "Hanoi Hilton."

McCain recalled in an emotional speech on the Senate floor Monday how Day and another POW, Norris Overly, had nursed the future senator back to health while imprisoned in 1967.
