Vice President of the United States Joe Biden on late Monday hinted at the possibility of entering the 2020 presidential campaign.

"I'm gonna run in 2020," Biden said when chatting with reporters after presiding over a Senate debate.

In an audio recorded by an NBC News correspondent, someone asked Biden what he will run for and the vice president said "for president."

"I'm not committing not to run. I'm not committing to anything. I learned a long time ago fate has a strange way of intervening," Biden enlarged on the idea.

Biden last October gave up the 2016 presidency bid after months' contemplation following his son Beau Biden's death, with concerns for "the emotional energy" of the grieving family.

"Your whole family is engaged, so for us, it's a family decision," said Biden in an interview with U.S. news organization America Media aired last September.

"I just have to be comfortable that this will be good for the family," he added.

The outgoing vice president has mounted unsuccessful presidential campaigns in 2008 and 1988. If Biden decides to run for president in 2020, he would be one of the oldest contestants for the presidency, at the age of 77.
