Vice President Kamala Harris has raised questions about former President Donald Trump's fitness for office, citing reports of his exhaustion on the campaign trail. Harris emphasized the importance of presidential stamina, asking if Trump's withdrawal from several interviews and events indicates he is unfit for another term. Trump's campaign has denied these claims, asserting that he maintains a vigorous schedule and has more energy than any other political figure. However, recent reports indicate he has canceled multiple media appearances, sparking debate about his health. Trump has responded by challenging Harris to take a cognitive test, asserting his own mental fitness. Despite the controversy, Trump continues to engage with media and rallies, though some interviews have been abruptly ended, fueling further speculation about his condition.
