Vice President Kamala Harris and former President Donald Trump are set to debate, with both campaigns intensively preparing. Harris has focused on preparing to counter Trump's expected attacks on her record and has criticized Trump's tendency to lie during debates. Trump, coached by former Democratic congresswoman Tulsi Gabbard, is likely to target Harris' record on economic and foreign policies. Gabbard, who has been a vocal critic of Harris and has endorsed Trump, has advised him to focus on Harris' perceived hypocrisy. The debate will be moderated by ABC's David Muir and Linsey Davis, and it marks a significant moment in the 2024 presidential campaign following Joe Biden's withdrawal. Both candidates aim to sway voters as early voting starts soon after the debate.
