Vice President Joe Biden hasn't ruled out the possibility of running for president in 2020, even though he will be 78 years old.
When a small group of reporters asked Biden about the possibility, Biden said he would, but hinted that he might be joking.
"Yeah, I am. I am going to run in 2020," Biden said on Dec. 5, according to CNBC. “For president and also, you know so, what the hell man, anyway."
The answer didn't sound like much of a formal declaration, even from a vice president known for being casual with the press. But when asked to elaborate, Biden answered with vagueness.
"I'm not committing not to run. I'm not committed to anything,” Biden said. “I learned a long time ago, fate has a strange way of intervening.”
If Biden were to become president in 2020, he'd be the oldest newly elected U.S. president in history.
Biden was considering running in the 2016 Democratic primary against Hillary Clinton, but his eldest son, Beau, died from cancer in May 2015, at the age of 46.
“My family has suffered a loss, and I hope there will come a time ... that sooner rather than later, when you think of your loved one, it brings a smile to your lips before it brings a tear to your eyes,” Biden said at the time.
Over the next few months, some members of the Democratic Party urged Biden to step into the primary, but the vice president ultimately decided against it.
“As my family and I have worked through the grieving process,” Biden said in a statement in October 2015, according to The Guardian, “I’ve said all along that it may very well be that that process, by the time we get through it, closes the window on mounting a realistic campaign for president.”
Biden ran for president twice -- in 1988 and 2008 -- but was never able to secure the Democratic nomination.
