During a press conference, President Biden mistakenly referred to Vice President Kamala Harris as 'Vice President Trump,' raising concerns about his mental fitness and ability to lead. This error follows other recent mix-ups, including confusing Ukrainian President Zelensky with Putin. Criticism and calls to end his re-election bid have been growing among supporters and Democratic colleagues, with concerns about his performance and electability against Donald Trump. Despite these challenges, Biden emphasized his confidence in Harris and his determination to stay in the race, citing his experience and past victory over Trump.
