Former US president Donald Trump has accused Piers Morgan of deceptively editing a video that appears to show the two men sparring over Mr Trump's false claims that he won the 2020 election.
Morgan posted brief excerpts on Wednesday of his interview with Mr Trump in a promotion for his new show, Piers Morgan Uncensored.
It appears to show the two men in a clash over the former president's false claims that the last US election was rigged.
"It was a free and fair election. You lost," Morgan says.
"Only a fool would think that," Mr Trump responds.
When Morgan asks Mr Trump if he thinks he is a fool, he replies: "I do now, yeah."
The brief, heavily edited video then appears to show the former president ending the interview and walking out.
But Mr Trump said in a statement that Morgan "attempted to unlawfully and deceptively edit his long and tedious interview with me". He said that the video "was doctored".
Morgan told The National that Mr Trump's claim is "fake news".
According to audio provided to US media outlets by the Trump team, the interview ended with the men exchanging pleasantries.
Mr Trump said the interview had gone over its allotted time by 20 minutes.
His spokesman, Taylor Budowich, said Morgan had used the former president to revive his career.
In March 2021, Morgan walked off the set of ITV's Good Morning Britain after a heated exchange about Meghan Markle. He later returned to the set but quit his job on the show.
Mr Trump never conceded the 2020 election and has continued to push false and disproven claims that the election was somehow stolen from him.
His misinformation culminated in the January 6, 2021 Capitol insurrection in which Trump supporters tried to overthrow the election results.
