United States President, Donald Trump, has changed course on his story about a pre-election hush money that was given to an American porn star who claims to have had relations with him before.

After previously claiming that he had no knowledge of the $130,000 payment that was made to Stormy Daniels, Trump is now saying that Daniels was paid for “false and extortionist” claims.

On Twitter, Trump said Cohen received a retainer every month “from which he entered into, through reimbursement, a private contract between two parties, known as a non-disclosure agreement.”

Trump’s tweets cited the arrangement came after Rudy Giuliani, one of his lawyers, said Trump paid back Cohen for the hush money that was given to Daniels days prior the 2016 presidential election.

His comments appeared to go against the President’s prior claims that he had no knowledge where the money came from.

During an appearance on Fox News Channel’s Hannity, Giuliani said the money to pay back Cohen had been “funnelled … through the law firm and the President repaid it.”

Asked if Trump knew about the plan, Giuliani said: “He didn’t know about the specifics of it, as far as I know.”

Giuliani later proposed to The Wall Street Journal that while Trump had paid back the $130,000, Cohen had settled the payment to Daniels without Trump’s knowing at the time.

Trump’s comments come after reports in United States media that federal investigators had documented Cohen’s phone lines right before raiding his offices, hotel room and home last month, confiscating records and documents.

Reports had earlier indicated that Cohen’s lines were wiretapped to let investigators hear the calls, but it was later clarified that investigators were only able to see who was calling who and not actually listen in on the conversations.

Undisclosed loan or reimbursement

Experts relayed that revelations over Trump’s knowledge of the payment brings to light a number of questions, including whether the money could be seen as reimbursement for a campaign expenditure.

Asked aboard Air Force One last month whether he knew about the payment, Trump curtly answered, “No.”

Trump also added he didn’t know why Cohen had made the payment or where he got the money.

In a phone interview however, Trump appeared to complicate matters even further in saying that Cohen represented him in the “crazy Stormy Daniels deal.”

The White House referred questions to the President’s personal legal team.

Giuliani, a former New York City mayor and ex-US attorney who took part in Trump’s legal team last month, said the President had repaid Cohen over several months, saying the payments continued through at least the presidential transition, if not into his presidency.

He also said the payment “is going to turn out to be perfectly legal” since “that money was not campaign money.”

No debt to Cohen is documented on Trump’s personal financial disclosure form, which was certified on June 16, 2017.

Giuliani also deemed the payment to Daniels as “a very regular thing for lawyers to do.”

Daniels’ legal representation, Michael Avenatti, described the comment as a “a stunning revelation”.

“Mr Trump evidently has participated in a felony and there must be serious consequences for his conduct and his lies and deception to the American people,” he said.
