A former White House cardiologist says Donald Trump looked "unwell" during his "manic" address to the nation.

Dr. Jonathan Reiner, who served as Vice President Dick Cheney's cardiologist for decades, made a series of posts to X as Trump addressed the nation. Though Reiner has been critical of the president in the past, he shared genuine concern for how "unwell" the 79-year-old Commander-in-Chief looks.

Taking to the social media platform, Reiner wrote, "No one should be happy to see the president like this. He looks unwell." In a post shortly before this, Reiner had written, "I'm seriously concerned about the health of the president."

Two further posts were shared by Reiner, one reading, "The pace of this address is manic." Another post from the cardiologist noted the dissonance between Trump's speech and the festive background. Reiner wrote, "The tone of this speech doesn't quite match the festive background."
