Former Fox News host Bill O'Reilly, who now produces an independent podcast and commentary program, has publicly advised President Donald Trump to take a month off to rest, citing what he described as clear signs that the 80-year-old president needs a break.

During his first year back in office, Trump has experienced several health-related issues, including swollen feet and legs, bruised hands, exhaustion, multiple doctor visits, and frequent verbal gaffes. These developments have fueled ongoing questions about whether the president can manage the demands of the office both mentally and physically. Presidential age and fitness have become a defining issue in American politics, with both of the 2024 cycle's major-party nominees having been the oldest presidential candidates in the nation's history.

Trump spent much of his time out of office criticizing former President Joe Biden — whom he labeled "Sleepy Joe Biden" — as too old for the presidency. He repeatedly questioned Biden's cognitive fitness and even promoted a conspiracy theory alleging that the Biden administration relied on an auto-pen to sign documents because Biden was allegedly unfit to sign them himself. The intensity of those age-related concerns ultimately contributed to Biden's decision to end his 2024 re-election campaign in July 2024, following a widely criticized debate performance.

Those sustained attacks on Biden's age and mental acuity are now drawing similar scrutiny toward Trump himself. The questions have become pronounced enough that some of Trump's own allies have reportedly begun questioning whether he is up to the job.

O'Reilly, who said he has known Trump for 35 years, noted that the president is visibly affected by his advanced age, according to a transcript published by Mediaite.

"I've noticed that he is hunching over a little bit and, uh, that's normal," O'Reilly said.

According to Banner Health, as bones weaken with age, the spine can compress and contribute to further muscle weakness, particularly when compounded by a lifetime of poor posture. Muscles in the upper back and neck can atrophy, and years of looking down at a desk or phone can make it increasingly difficult to resist the forward pull of gravity.

O'Reilly, who is four years younger than the president, acknowledged that aging inevitably brings health challenges for everyone.

"I can't even bore you with the stuff I got to deal with. And I, I was actually feeling sorry for myself the other day, and I never do that," O'Reilly said.

"But I know the president a little. So, my advice to Donald Trump is to take the next month off, if you can," he continued. He recommended that Trump "get into an environment where you like, golf and relax. You got to deal with Iran. I understand that. Everybody understands it. But you can do that on the phone, and you can do that with your people coming."

"But you need a breather," O'Reilly added. "I need a breather, and I'm going to build it into August. But he needs a breather much more than I do, OK?"

O'Reilly also stated that he wishes Trump well, as he does for all presidents, expressing respect for the office itself. He named several predecessors, including Joe Biden, Barack Obama, and Jimmy Carter.

The advice marks a notable contrast with O'Reilly's earlier commentary. During his tenure at Fox News, he frequently criticized President Obama for taking expensive vacations while the economy was still recovering from the 2007–2008 financial crisis.

In a 2011 column, O'Reilly wrote: "Creative people need downtime in order to operate at their best. Bad decisions are often made when a person becomes exhausted. Presidents are under siege to deal with one problem after another. Everybody wants something. The job never stops." At the time, he was arguing that Obama was failing to set a good example and was spending tourism dollars in places like Martha's Vineyard rather than elsewhere. He closed that column by telling Obama to enjoy himself, "but [he] shouldn't get used to it."
