In a high-stakes press conference, President Joe Biden mistakenly referred to Vice President Kamala Harris as 'Vice President Trump,' adding fuel to concerns about his cognitive abilities. This gaffe occurred shortly after Biden had confused Ukrainian President Volodymyr Zelensky with Russian President Vladimir Putin at an earlier event. The press conference was intended to showcase Biden's capability to handle unscripted questions, following a weak debate performance against former President Donald Trump. Biden's missteps have intensified calls from some Democrats for him to step aside in favor of another candidate. Despite these calls, Biden remains adamant about continuing his reelection campaign and acknowledged his debate shortcomings, hinting at avoiding late-night public events to prevent further mistakes.
