The cardiologist for the late Vice President Dick Cheney said Wednesday he was “seriously concerned” because President Donald Trump looked “unwell” during his speech.

Reiner, now a CNN medical analyst, critiqued the president’s tone and “manic” pace before zeroing in on Trump’s physical state.

“I’m seriously concerned about the health of the president,” the doctor wrote on X.

“No one should be happy to see the president like this,” he added. “He looks unwell.”

The physician, who treated Cheney’s severe heart disease when he was vice president and eulogized him after his death last month, did not delve into specifics.

Trump looked "unwell," the doctor asserted.

Previously, Reiner aired suspicions over what the Trump White House called his “preventative MRI.”

Trump faces skepticism over his routine boasts of good health. A New York Times report called out a significant dip in his activity level, prompting him to lash out at the newspaper. He even called the publication “seditious, perhaps even treasonous” for its coverage of his health.
