Donald Trump is back in the history books—this time as the oldest U.S. president to take the oath of office. At 78 years, seven months, and six days old, he reclaimed the title on Monday, surpassing Joe Biden, who was 78 when he was sworn in back in 2021. When Trump first became president in 2017, he was 70, making him the oldest to hold the office at the time. But Biden, now 82, broke that record four years later. Now, Trump has edged him out by just over five months. Age has been a hot topic in recent elections. Biden faced criticism last summer after a shaky debate performance, with some calling for him to step aside. After he dropped out, Kamala Harris, 60, became the Democratic nominee, setting up a generational contrast with Trump. Before Trump and Biden, Ronald Reagan held the record as the oldest president. He was 69 when he first took office in 1981 and 77 when he left after his second term. It’s clear that age is no longer just a number in U.S. politics—it’s a talking point that keeps coming up. Whether it’s experience or energy, voters are paying attention. ---
