Donald Trump has said Joe Biden is 'not fit to run for president' and 'certainly not fit to serve'. Trump, who this week accepted the Republican nomination for the 2024 presidential election, accused Mr Biden of gaining the presidency through 'lies, fake news and not leaving his basement'. He suggested, without providing evidence, that Mr Biden's doctor 'knew that he wasn't capable of being President'.
' The former president has repeatedly alleged - without evidence - that the 2020 presidential election was fraudulent, initially refusing to accept his loss and spreading lies that victory was stolen from him. The turmoil culminated in the riot at the Capitol on 6 January 2021, when Trump loyalists violently broke into the building, attacked police officers and disrupted the congressional counting of electoral votes.
