US President Joe Biden went to the hospital on Wednesday for his final annual medical examination before the November election, facing increased scrutiny over his fitness and mental acuity at 81 years old. The White House will release a summary of the test results from the Walter Reed medical facility later in the day, with many interested in the health of America’s oldest leader. Biden, set for a potential rematch with former President Donald Trump, took a helicopter ride to the medical center. Last year, Biden received a clean bill of health with a cancerous lesion removal, and his doctor said he remained healthy and fit for his duties. Biden has faced criticism over his age and cognitive abilities, with Trump also facing scrutiny over verbal gaffes and memory issues. Trump released a note declaring his health to be excellent but lacked details on specific test results from his last physical examination.
