Secretary of State John Kerry said in an interview airing Wednesday that he won't run for president again.

Kerry's stint as secretary of state has rekindled some talk that he might run again. But the 70-year-old former Democratic candidate told CNN's Jake Tapper that it won't happen.

"One of the joys of this job is I'm out of politics," Kerry said.

Tapper asked him to clarify: "Forever?"

Kerry responded: "I'm out of politics. I have no plans whatsoever. This is my last stop. I'm going to serve the country in the extraordinarily privileged position the president has given me -- the great challenges that I have -- and move on."

Kerry said he also won't comment on anybody else who might run.
