Sen. John McCainJohn Sidney McCainHow House Republicans scrambled the Russia probe The Hill's 12:30 Report The Hill's Morning Report - Sponsored by CVS Health - A pivotal day for House Republicans on immigration MORE (R-Ariz) said he has no plans to run again for the White House.

Speaking to The Arizona Republic newspaper, McCain said he had received "a spate of emails and letters and phone calls" urging him to run since the government shutdown.

But he said he's focused on whether to run for a sixth term in the Senate, not for president.

“As you know, I’m seriously thinking about running for reelection to the Senate," he said. "But I think, in the words of the late Morris K. Udall, as far as my presidential ambitions are concerned, ‘The people have spoken — the bastards.’"

McCain will turn 80 in 2016, and the two-time presidential contender insisted he has no plans to launch a third bid.

“I can assure you, I don’t see it,” McCain said. “It’s not on my radar.”

He still hasn't decided, however, on whether he'll run for reelection in 2016.

McCain's retirement would open up a contentious fight for his seat, which he's held since 1986.
