Just six months after having his annual physical at Walter Reed Medical Center, President Donald Trump is headed back to the hospital Friday for what the White House is calling a "routine yearly checkup," prompting critics to ask just how healthy he reall is Newsweek reports. Trump, who went to Walter Reed for his physical on April 11, is the oldest sitting president in U.S. history at 79 years old. His upcoming visit there comes among public scrutiny of his health, ranging from questions about cognitive issues to bruising on his hands (the White House doctor has attributed the latter to deep vein thrombosis). "But despite persistently questioning Biden’s physical and mental capacity, Trump has long kept basic details about his own health secret," Newsweek says. Following his April physical, Trump's doctor said he “remains in excellent health, exhibiting robust cardiac, pulmonary, neurological, and general physical function” and that his “active lifestyle continues to contribute significantly to his well-being.” A recent poll by YouGov showed 49 percent of Americans think Trump is too old to be president, 63 percent believe his health and age affect his ability to perform his job. Forty-nine percent believe he is suffering a cognitive decline. Over 8,000 people signed a petition in July calling for Trump to release his full medical records, something he has yet to do. Following White House press secretary Karoline Leavitt's announcement that Trump would be visiting troops and stopping by Walter Reed "for his routine yearly check up," social media sleuths raised red flags. Journalist Prem Thakker wrote on X: “White House says Donald Trump will visit Walter Reed Medical Center on Friday. While there, he will ‘stop by for his routine yearly check up.’ But…Trump had his annual check up already. 5 months ago. On April 11.” Cardiologist Dr. Jonathan Reiner wrote on X: “The White House announced that the president will go to Walter Reed on Fri for his ‘yearly check up’. It’s a bit early, as he’s not due for his annual exam until April.” Liberal influencer Brian Krassenstein wrote on X: "BREAKING: Donald Trump Visiting Walter Reed Medical Center Tomorrow for what the WH says is "an annual checkup". Problem... He had his annual checkup on April 11th, less than 6 months ago. What is going on?" Time wrote on X: "Trump to get second ‘yearly’ health screening in months" Geoff Brown wrote on X: "Cankles is heading back to Walter Reed. JD and the tech bros are waiting in the wings." Policy advisor Adam Cochran had the most questions, asking, "Why is the White House lying and when will the press push on it? They claim Trump is having his “annual checkup” at Walter Reed Friday. The problem is that he already had that back in April which they released results for. The annual checkup is a long set of tests and so takes significant time - what will Trump actually be doing at that time at Walter Reed? -Increasing droop face -increasing memory problems -randomly missing from camera for up to a week at a time And now: -lying about hospital visits. How the HELL isn’t the press pool pushing on these obvious lies?!"
