US President Joe Biden responded to critiques about his age in a spirited speech, affirming his determination to secure re-election in November following concerns over his performance in a recent debate with Republican rival Donald Trump. Addressing supporters in North Carolina on Friday, Biden acknowledged his age, stating, "I know I"m not a young man, to state the obvious." Despite admitting to physical limitations and debating challenges, Biden asserted his confidence in his ability to lead, declaring, "I know how to tell the truth and I know how to do this job." At 81 years old, Biden"s shaky debate performance raised doubts among some Democrats, prompting discussions about his candidacy. However, Biden"s campaign team remains resolute that he is fit for office, dismissing calls for him to step aside. While acknowledging Biden"s debate stumbles, campaign surrogates emphasized his substantive responses compared to Trump"s, aiming to reassure supporters and quell uncertainties within the party. Former President Barack Obama defended Biden, characterizing the debate as a typical political setback, emphasizing the election remains a choice between Biden"s dedication to ordinary citizens and Trump"s self-serving agenda. Despite internal concerns and external criticisms, Biden"s campaign continues to show fundraising resilience, raising millions in the aftermath of the debate, underscoring ongoing support for his candidacy. Biden is scheduled to meet with additional donors, further signaling his campaign"s determination to press forward amidst challenges. — BBC
