(CNN) - For now Vice President Joe Biden is focused on the president's reelection effort, but come 2016 he may be whistling a different tune.
The former presidential candidate and Delaware senator left the door open to running for president again in an exclusive interview with CNN Chief Political Correspondent Candy Crowley.
"I'll make up my mind on that later," Biden said in an interview set to air Sunday on CNN's "State of the Union." "I'm in one of the, probably the best shape I've been in in my life … I'm doing pretty well. I'm enjoying what I'm doing, and as long as I do, I'm going to continue to do it."
"And we'll find out, you know, let's get the president reelected," Biden added.
