Vice President JD Vance said in an interview published by USA Today that he is prepared to assume the presidency should an unforeseen tragedy prevent President Donald Trump from completing his term, while stressing that the president remains in “incredibly good health.” Vance, who turned 41 earlier this month, cited his roughly 200 days—about seven months—of “on-the-job training” as evidence of readiness, saying he “can’t think of better on-the-job training” than serving as vice president. He added that Trump, 79, routinely works longer hours than his younger staff and shows “incredible energy.” The remarks follow renewed public attention to Trump’s age and a July disclosure by the White House that the president has chronic venous insufficiency, a mild and common circulatory condition that causes leg swelling but was deemed benign by his physician. Vance said he is confident Trump will serve out the remainder of his term but stands ready if required.
