(CNN) - Arizona Sen. John McCain said Friday the Nobel Committee's decision to award President Obama the Peace Prize was likely based on expectations, not accomplishments.
"I can't divine all their intentions, but I think part of their decision-making was expectations," McCain told CNN's John King. "And I'm sure the president understands that he now has even more to live up to."
But Obama's former rival for the White House said he was happy with the decision.
"I think all of us were surprised at the decision," he said. "But I think Americans are always pleased when their president is recognized by something on this order."
John King's full interview with McCain will air Sunday on State of Union at 9 a.m. ET.
