President Trump once made Stormy Daniels spank him with a Forbes magazine with his photo on the cover — and sit with him for hours watching “Shark Week,” the porn star told a political operative, according to a report.

In 2009, Daniels was mulling a Senate run in Louisiana and working with local political consultants about potential donors.

Trump was on her list — and his name was one of the contacts in her phone, one operative told Andrea Dubé, a Democratic political consultant in an email.

“She says one time he made her sit with him for three hours watching ‘Shark Week.’ Another time he had her spank him with a Forbes magazine,” the consultant told Dubé in a series of emails, which were obtained by Mother Jones.

Both operatives confirmed they exchanged the emails.

The consultant who wrote to Dubé told Mother Jones that Daniels said Trump spanked her with Forbes magazine that featured himself on the cover.

An issue from 2006 includes Trump and two of his kids on the cover, with the headline “The 400 Richest People in America.”

Daniels’ run would have been against Louisiana Sen. David Vitter, who became embroiled in a sex scandal a couple years earlier when his phone number was found in the records of the “D.C. Madam” accused of running a prostitution ring in the capital.

The Wall Street Journal said last week that Trump’s lawyer paid Daniels $130,000 weeks before the presidential election to keep quiet about their 2006 tryst.

On Thursday, the newspaper reported that the lawyer, Michael Cohen, paid her through a private Delaware company, called Essential Consultants LLC, that he’d created on Oct. 17, 2016.

Cohen used a bank account linked to the company to pay Daniels, the report says.

Both Daniels and Trump have denied having an affair.
