Stormy Daniels says she and her daughter were violently threatened over Donald Trump affair story in explosive TV interview

Porn star Stormy Daniels claimed she and her daughter were threatened after trying to tell her story about an alleged affair with US President Donald Trump during a US TV interview on Sunday night (local time).

She also shared details about the sexual encounter she claims to have had with the former Celebrity Apprentice star in 2006 during the interview with Anderson Cooper on CBS' 60 Minutes.

Ms Daniels, whose real name is Stephanie Clifford, alleges being aggressively threatened in a car park when she initially tried to tell the story of her relationship with Mr Trump in 2011.

"A guy walked up on me and said to me, 'Leave Trump alone. Forget the story'," she told CBS.

"He leaned around and looked at my daughter and said, 'That's a beautiful little girl. It'd be a shame if something happened to her mom.' And then he was gone."

"I was rattled, I remember going into the workout class and my hands were shaking so much I was afraid I was going to drop [her daughter]."

Ms Daniels' daughter was with an infant at the time she says she received the threat on her way to a fitness class.

She says she'd tried to sell her story to In Touch magazine but they were stalling because Mr Trump's lawyer had threatened to sue.

Prior to detailing the alleged carpark threat, Ms Daniels sexual relationship with Mr Trump had been the focus of heated discussion surrounding her.

She revealed to CBS that she and Mr Trump only had sex once, and they did not use a condom. She also claims she spanked Mr Trump with a magazine that featured him on the cover.

Ms Daniels was paid USD $130,000 (NZD $180,000) by Mr Trump's lawyer immediately prior to the 2016 presidential election in an agreement to keep quiet.

However, she is now suing Mr Trump, arguing their deal is void.

She has offered to return the money so she can openly discuss their interactions.

Mr Trump denies the affair, and his lawyers are threatening her with "financial ruin".
