Vice President Biden was confronted Tuesday on his possible 2016 run for president. 

On a visit to Panama, Biden greeted the country’s president, Ricardo Martinelli, as the two entered his presidential palace.

Biden told the Panamanian president he looked good, as people not running for office never do, according to the White House pool report.

Martinelli assumed office in 2009, and is limited to a five-year term.

“You’re going to be running next time,” Martinelli replied.

Biden chuckled, the report said, and appeared somewhat embarrassed.

“Oh, we’ll talk about that,” he responded.

The vice president has not yet concretely said whether or not he intends to run for president in 2016. He did recently visit Iowa, however, which is usually the first stop that a presidential candidate makes because of its significance to the primary season.

Biden previously ran for president in 2008 and 1988. He served in the Senate for 36 years, after first being elected in 1972.

The former Delaware lawmaker turns 71 years old on Wednesday, which would make him almost 74 in the 2016 election.

Hillary Clinton, 66, is considered to be the front-runner for the Democratic ticket that year if she decides to run again. She will turn 69 shortly before that election.
