Donald Trump’s campaign manager Kellyanne Conway said Wednesday night that the GOP presidential nominee might need to release more detailed medical records.

In a wide-ranging interview with MSNBC’s Rachel Maddow, Conway was asked if Trump owes the American people an actual medical report that’s more credible than the one already released.

“Perhaps,” she responded.

She then commented on Hillary Clinton’s health, which has been questioned by people like former New York City Mayor Rudy Giuliani who’s been stirring talk about conspiracy theories.

“It’s not an issue that I care to comment on, because I’m not a doctor,” Conway said about Clinton’s health. “She’s not my patient. And I can just tell you what I see with my own two eyes, which is I don’t see someone who really enjoys campaigning the way he does.”

Conway said Trump has a “crazy, ridiculous pace for a man his age” and that it’s “very difficult” for younger staffers to even keep up with him.

“I confess, I don’t know when he sleeps,” she said.

Trump released some medical information last December, which came from Dr. Harold N. Bornstein of Lenox Hill Hospital in Manhattan.

“Over the past 39 years, I am pleased to report that Mr. Trump has had no significant medical problems,” Bornstein wrote. “If elected, Mr. Trump, I can state unequivocally, will be the healthiest individual ever elected to the presidency.”

That doctor, however, may not have taken into account George W. Bush, who was 17 years younger than Trump when he took office, ran a 7-minute mile pace and still mountain bikes. Or Teddy Roosevelt, a wrestler, boxer, tennis player and rough rider, who was 43 years old when he became president. Or President Obama, who was 23 years younger than Trump when he took office, and still plays a mean game of pickup basketball.
