US vice-president and Democratic presidential candidate Kamala Harris "invited" former US president and Republican presidential candidate Donald Trump to another televised debate with her on social media on September 21, but Trump refused, saying the debate was "too late". Harris challenged Trump on social media X: "I will be happy to participate in the second presidential debate on October 23. I want Trump to participate with me." Trump rejected the "invitation" at a campaign rally in Wilmington, North Carolina on the 21st, responding: "The problem with having another debate is that it is too late, and the voting has already begun."
