Republican US presidential candidate Donald Trump said that "Biden is not too old" to prevent him from seeking a second presidential term, but he pointed out that the biggest problem is that he is "incompetent."

The former US President's statements came during an interview with NBC that will be broadcast on Sunday, in the midst of an ongoing debate in the United States about the aging of the political class, which is a major factor in the 2024 elections.

At the due date, Biden will be 82 years old, while Trump will be 78 years old.

Polls indicate greater fear among Americans about Biden's age, despite the small age difference between the two men.

A poll showed that 75 percent of respondents doubted the Democratic president's ability to assume the duties of office for a second term.

At the end of his term, Trump was the second-oldest American president (Ronald Reagan was 77 years old at the end of his term), which constitutes a challenge for the real estate mogul, who, despite this, continues to call the current president “Sleepy Joe.”

If he wins the presidency in the 2024 elections, Trump will be 82 years old when his term ends.

"Some of the world's greatest leaders were eighty," Trump said in the interview, adding, "By the way, I'm not even close to being eighty."

He continued, "Biden is not very old, but I think he is incompetent, and this is a bigger problem."

Biden's age is a major obstacle to him, despite the efforts made by the White House to market his economic, social and diplomatic successes.

During Biden's last medical examination in February, his doctor described him as "energetic" and in "good health." However, Seneh continues to concern voters in a country that places great importance on youth.

The president now walks very cautiously and stutters, and since he is always under the spotlight, there is no escape.

In the interview, Trump said that his age does not cause him concern, noting that his parents lived a long life.

"Genetically, it's a good thing," he continued.
