President Joe Biden has rejected calls for an independent cognitive evaluation to reassure voters of his mental fitness following a poor debate performance against Donald Trump. In an interview with ABC News, Biden, 81, claimed he undergoes a 'cognitive test every single day' and attributed his debate struggles to exhaustion and a bad cold, not an underlying condition. He acknowledged his performance was a 'bad episode,' taking full responsibility while emphasizing his capacity to continue his role. Critics on social media have expressed concern over his ability to remember if he watched the debate replay, questioning his preparedness for the campaign. Biden remains committed to his reelection bid, asserting that he is the best candidate to defeat Trump.
