US President Joe Biden, who will turn 80 next November, announced that he "intends" to run for another presidential term in 2024, but he made it clear that he has not made a formal decision to do so yet.

When asked about this issue on MSNBC, the Democratic president said, "I haven't made the decision officially yet, but I intend to run again and we have time to make that decision."

When asked if his wife, Jill Biden, supports him running for president again, he indicated that she supports the idea.

"My wife thinks we are doing something very important and that I shouldn't give up on it," he said.

Biden, the oldest American president, celebrates his 80th birthday on November 20.

He will be 82 at the beginning of his second term if he runs and wins, and 86 at the end of his term, which is a very sensitive issue in his Democratic camp.

In September, the Democratic president said he had not made up his mind about running for the US presidential election in 2024. "Have I made the final decision to run? Have to wait," he said in an interview.

Biden and his party are preparing for the November 8 midterm elections, a traditionally tough test for any incumbent president.
