The post comes after the Harris campaign said the Democrat is ready and willing to participate in another debate, following the pair's first meeting on a debate stage in Philadelphia on Tuesday.
"When a prizefighter loses a fight, the first words out of his mouth are, 'I want a rematch,'" Trump wrote, equating Harris to a boxer who has lost.
He claimed that polls show that he won the debate, but snap polls taken in the immediate aftermath indicated voters felt Harris performed more strongly.
The former president added that all of the "problems caused by Kamala and Joe [Biden]" were "discussed in great detail" during his first debate against Biden in June and then in his second debate against Harris.
"There will be no third debate!" he ended his post, using all capital letters.
