Republican presidential candidate Donald Trump said on Thursday he would not participate in another presidential debate against Kamala Harris ahead of November's general election after several polls showed his Democratic rivals winning their debate earlier this week.

"THERE WILL BE NO THIRD DEBAT!" wrote the former president on the Truth Social social media website.

Prior to the debate with the incumbent Vice President Harris, former President Trump had contested in June with the Democratic presidential candidate at the time, Joe Biden.

"I think this is the best debate I've had personally," Trump said in a'spin room' after Tuesday's debate.

Trump said Harris "wanted to have another debate because he was beaten tonight, but I don't know if we're going to have another debate."

Trump was again not committed when asked Fox News if he would agree to another debate with Harris.

"I have to think about it, but if you win a debate, I think maybe I don't need to," he said.

Although Trump praised his performance against Harris, six Republican donors and three Trump advisers who spoke to Reuters earlier this week said they thought Harris had won the debate primarily because Trump could not deliver his message.

According to Nielsen data, the debate caught the attention of 67.1 million television viewers.

Harris, speaking at a rally shortly after Trump's post aired, said: "I believe we owe it to voters to hold other debates."

While Trump said in his post polls showed he won the debate, several surveys showed respondents thought Harris had won better.

Among voters who say they have heard at least something about Tuesday's debate, 53 percent say Harris won and 24 percent say Trump won, according to a Reuters/Ipsos poll released on Thursday.

The poll showed 54 percent of registered voters believed the single debate between Trump and Harris was sufficient, while 46 percent wanted a second debate.

The majority of debaters say Harris outperforms Trump, according to a CNN quick poll released shortly after the debate. YouGov showed 54 percent of those surveyed said Harris won while 31 percent said Trump was the winner.
