caption="Sen. John McCain spoke to reporters in Arizona on Friday."](CNN) - Sen. John McCain has already received a signed copy of Sarah Palin's new memoir "Going Rogue," but the former Republican presidential nominee hasn't read it yet.
"I've just received a signed copy from her yesterday, so I will read it with interest," the senator told reporters Friday in his home state of Arizona.
While the book contains a healthy dose of score-settling aimed at former McCain campaign aides, the senator stressed that he was "proud and honored" to have had Palin as his running mate.
"One of the things about campaigns that lose, there's always mistakes made and the campaign that wins is always the perfect campaign," he said. "I'm proud of the campaign we ran. I'm proud of Sarah Palin and we continue to have a great and wonderful relationship. So, I'm very proud of the campaign we ran and I have moved forward."
When asked if the book has become "a nuisance," McCain responded no. "It is the usual background noise," he said.
He also responded to a question he has heard over and over again since the campaign ended: Can Palin be a viable presidential candidate herself in 2012?
"Sure," he said. "I think there are a number of viable candidates out there. I think that Sarah Palin is obviously one of them and we'll start through the process in about a year or so of selecting our nominee, but I think she's a very strong force in the Republican Party. I can't predict who's gonna get the nomination but I certainly think she would be competitive."
