A former Obama administration health official is speaking out against a new report from President Trump‘s White House physician.

After Trump’s physician, Sean Conley, reported on Friday that the president is “in very good health” and would “remain so for the duration of his Presidency, and beyond,” Ronald Klain, who was appointed by former President Obama to oversee the response to the Ebola crisis, slammed Conley for what he saw as a misleading claim.

“No doctor can predict someone’s future health,” Klain wrote on Twitter on over the weekend.

“This is a disgrace to an office with a great tradition of professionalism. Just another institution turned into a joke by a President determined to make anyone willing to submit an instrument of his lies.”

Conley’s report came after Trump, 72, made a four-hour visit to the Walter Reed National Military Medical Center last Friday for his second physical examination as president.

The report did not contain even basic information about the president’s health, including his height and weight. It also omitted any specific information on the findings, though noted that “reports and recommendations are being finalized.”

Trump’s first exam as president was in January 2018, after which former White House physician Dr. Ronny Jackson — who faced shocking allegations of misconduct in April 2018 after Trump nominated him for Veterans Affairs secretary — said Trump was “currently very healthy,” but “would benefit from a diet that is lower in fat and carbohydrates, and from a routine exercise regimen.” (Jackson denied the allegations.)

The physician — who the president recently promoted — also said Trump’s cholesterol was slightly elevated, but he was prescribed Crestor to address that, and otherwise “his cardiac health is excellent.”

Like Conley’s letter from Friday, Jackson’s 2018 report was effusive and made similar large claims, saying that Trump had “incredible genes” and adding that “if [the President] had a healthier diet over the last 20 years he might live to be 200 years old.”

Meanwhile, while he was on the campaign trail in 2015, Trump allegedly dictated his own health report.

“He dictated that whole letter,” Harold Bornstein, Trump’s longtime personal doctor, claimed to CNN in May 2018. “I didn’t write that letter.”

When Bornstein’s typo-littered letter praising Trump’s “physical strength and stamina” was released by his campaign in December 2015, many noticed that its hyperbolic language bore a striking resemblance to the president’s own way of speaking.

Bornstein described Trump’s blood pressure of 110/65 as “astonishingly excellent” and declared, “If elected, Mr. Trump, I can state unequivocally, will be the healthiest individual ever elected to the presidency.”

Trump himself has referenced his health in interviews. In an odd exchange with Good Morning Britain host Piers Morgan in July 2018, the President was asked whether he’ll run for re-election and seemed to imply that his health could stop him from running.

“Well, I fully intend to,” Trump told Morgan in the televised interview. “It seems like everyone wants me to.”

But earlier in the conversation, Trump seemed to oddly admit he might not be on the ballot.

“Well, you never know, er, what happens with health and other things. I mean, you know, let’s face it…” said Trump before Morgan interjected.

“You fit? You look fit,” Morgan told Trump.

“I feel good,” replied Trump, who has had a years-long, well-documented love affair with fast food.
