Former First Lady Jill Biden expressed concern during an interview with CBS News regarding her husband, Joe Biden, during the 2024 presidential debate against Donald Trump. She stated that she was frightened and thought he might be having a stroke due to his performance, where he appeared to stumble over his words and seemed frail. This statement contrasts with her earlier comments after the debate, where she praised Joe Biden's performance.
Joe Biden later withdrew from the presidential race a month after the debate and endorsed Kamala Harris as the Democratic nominee. Following the debate, Joe Biden was diagnosed with Stage 4 prostate cancer, which Trump criticized, questioning the transparency surrounding Joe Biden's health disclosures. While presidents are not required to disclose medical information, they may do so at their discretion. Trump has also criticized Joe Biden for not undergoing a cognitive test during his physical examination in 2024. Recently, Trump announced that his own six-month physical went well, although he did not specify the exams he underwent.
