Michael Wolff abruptly left an interview with an Australian TV news program on Sunday after he was asked about his claims President Donald Trump was having an affair.

Wolff suddenly appeared to be having technical difficulties, said he couldn’t hear the question, and left his seat.

Alternative footage showed the audio signal was working without issues.

Last week Wolff went back on his claims Trump was having an affair after saying he was "absolutely sure" about it.

The author of "Fire and Fury: Inside the Trump White House" walked off an interview with an Australian breakfast television program on Sunday after being questioned over his claims US President Donald Trump was having an ongoing affair.

Michael Wolff, who wrote the best-selling exposé of Trump’s administration and his presidency, was almost five minutes into the interview when the "Today" show interviewer Ben Fordham asked Wolff about the claims.

"You said during a TV interview just last month that you are 'absolutely sure' that Donald Trump is currently having an affair while president behind the back of the first lady, and I repeat you said you were 'absolutely sure,'" Fordham said.

"Just last week however you backflipped and said I quote 'I do not know if the president is having an affair.' Do you owe the president and the first lady an apology, Mr. Wolff?"

Despite trying to interrupt, Wolff began complaining of technical difficulties and finally responded by saying, "I can’t hear you."

Fordham repeated his question. This time louder.

Wolff tried to get the help of a crew member from the set he was on in London, saying: "I'm not getting anything."

When Fordham asked, "You're not hearing me, Mr. Wolff?" the author said, "No, I'm not getting anything."

Wolff then removed his earpiece and left. A stunned Fordham said, "It looks like the interview may be over."

Once the live cross ended, Fordham's cohost Georgie Gardner said, "Gee, that was an unfortunate question to miss, wasn't it?"

"I think he may have heard it," Fordham replied.

Later, the show revisited the footage from the UK studio and found the audio to be coming through clearly.

Fordham's line of questioning related to comments Wolff made last month in which he strongly implied the president was having an affair with the US ambassador to the United Nations, Nikki Haley.

That claim was denied by Haley, who called it "highly offensive" and "disgusting."

Last week Wolff backed away from the idea, telling a Dutch TV show "I do not know if the president is having an affair."
