Trump abruptly ends NBC interview after clash over 'rigged election' claim

US President Donald Trump abruptly walked out of an interview with NBC after being repeatedly challenged on several claims by the show's presenter Kristen Welker.

During the interview, which aired on Sunday's Meet The Press, the president claimed both the current primary elections in California and the 2020 presidential election were "rigged".

When pressed for evidence on California's vote by Welker, he said: "All I have to do is look, and I listen."

After the presenter replied "that's not evidence", Trump accused the media of being "crooked", before ending the interview: "Sorry, let's call it quits because I've had enough."

The president has had a fraught relationship with traditional media outlets, often accusing them of bias against him.

The interview, set in a barn as Trump appeared at an event with farmers in Wisconsin, was delayed repeatedly due to technical difficulties and rain hitting the metal roof. NBC reported that he walked out 50 minutes after sitting down for it on Friday.

Much of the interview involved Welker questioning Trump over the conflict with Iran, with him insisting the US needed to act to stop Iran from getting a nuclear weapon and that it would not be "an endless war".

"We're there for a few months and the threat is largely over," he said.
