President Joe Biden said in a new interview that questions about his age are "totally legitimate" as he is expected to announce a run for reelection in 2024.

Biden shared the remarks in an interview with ABC News host David Muir on Sunday.

The comments

“It’s legitimate for people to raise issues about my age,” Biden told Muir.

“It’s totally legitimate to do that. And the only thing I can say is, ‘Watch me,'" he added.

After the president’s historic week on the global stage and so much to manage in the U.S., @DavidMuir sits down with Pres. Biden at the White House for an exclusive one-on-one interview.

The age issue

Biden, 80, is already the nation's oldest sitting president. He would be 82 at his reelection and 86 at the end of his second term if he is reelected.

"Republican Nikki Haley in her opening pitch for her 2024 presidential bid earlier this month insisted that anyone over 75 should be subjected to a mental competency test," the Hill reported.

Former President Donald Trump responded to Haley's call positively, saying he would be glad to take any such test. Trump is 76.

Others have blasted Haley's challenge for older politicians, including Sen. Bernie Sander (I-VT), who called the measure absurd.

"He's not done"

The report also comes as First Lady Jill Biden seemed to dispel rumors about 2024 by saying, "He's not done," when asked about her husband's plans for reelection.

In addition to Trump and Haley running for the Republican nomination, Marianne Williamson said last week that she will run against Biden as a Democrat. She previously ran against him during the 2020 election. Other Democrats, including Sen. Joe Manchin (D-WV), have continued to leave the door open for a run for the White House.

The questions about Biden's age are expected to continue as the 2024 campaign moves forward, with many voters hoping an alternative candidate will emerge. Other potential Republican contenders include former Vice President Mike Pence, former Secretary of State Mike Pompeo, and Florida Gov. Ron DeSantis. Vivek Ramaswamy also jumped into the campaign earlier this month to add to the growing number of current and potential contenders.
