Trump Turns 80, Becoming Second-Oldest President to Serve in Office

President Donald Trump turns 80 on Sunday, June 14, reaching a milestone that places him among the oldest people ever to occupy the Oval Office and reviving a debate over age and fitness that dogged his predecessor. Born in 1946, Trump was already the oldest president ever inaugurated when he took the oath in January 2025 at 78 years and 220 days, and he is on track to leave office as the oldest president in U.S. history.

Only Joe Biden, who was 82 when he left the White House in 2025, has served at a more advanced age. Trump is set to surpass Biden’s record in the summer of 2028, near the end of his term, when he would be roughly 82 and a half. The symmetry has not been lost on his critics, who spent years questioning Biden’s acuity and now turn the same lens on Trump.

The White House has worked to project vigor. Trump’s physician reported after a recent examination that the president “remains in excellent health,” citing strong cardiac, pulmonary and neurological function and declaring him fit to carry out all duties of the office. Trump has repeatedly touted a perfect 30-out-of-30 score on a cognitive screening test, which he has described as a sign of “extreme intelligence,” and has even suggested future candidates be required to take such exams.

Aides have responded to age concerns with a strategy of omnipresence, keeping the president in near-constant public view to contrast with Biden’s lower profile. The approach has produced its own stumbles: Trump appeared to nod off during an NBA Finals game while eating, returned to the White House after 2 a.m. on at least one recent night, and the next morning delivered a lengthy critique of a Wall Street Journal editorial by phone.

In a global context, Trump’s age is far from unusual among heads of state. A Pew Research Center analysis found that as Trump turns 80, only 16 of 186 national leaders are older, with Cameroon’s Paul Biya, 93, and Saudi Arabia’s King Salman, 90, topping the list. Still, the U.S. presidency carries singular demands, and longevity in the role invites scrutiny that few other offices attract.

The birthday arrives during a consequential stretch of Trump’s second term, with the administration navigating a tense standoff in the Middle East and a slate of domestic battles. Sunday’s milestone, falling a day after his predecessors’ generation marked its own anniversaries, is likely to sharpen a question voters have weighed before: how age and stamina factor into the highest office in the land.
