Trumps första brottmål inleds den 25 mars

On January 12, 2018, The Wall Street Journal reported that in October 2016, just before the 2016 United States presidential election, Michael Cohen, lawyer for then-presidential candidate Donald Trump, arranged a payment of US$130,000 to pornographic film actress Stormy Daniels to stop her disclosing an affair she and Trump allegedly had in 2006. Daniels had signed a non-disclosure agreement (NDA). At first, Cohen denied Trump had the alleged affair and sought to suppress the allegation based on the NDA, but a month later publicly acknowledged making the payment. Besides allegations surrounding the details of the affair itself, the acknowledged payment raised legal and ethical questions as to whether the payment violated federal campaign finance laws, either because the payment was not duly disclosed as a campaign contribution or because campaign funds may have been used towards the payment. On February 13, Cohen said he paid the money out of his own pocket, not as a campaign contribution; and that neither The Trump Organization nor the Trump campaign reimbursed him for making it. On April 5, Trump said he had no knowledge of Cohen's payment; but on April 26 admitted for the first time that Cohen represented him in "the Stormy Daniels deal". On May 2, Trump's new lawyer Rudy Giuliani said that Trump had reimbursed Cohen for the payment.In August 2018, Cohen pleaded guilty to eight criminal charges, including a campaign finance violation for Daniels's payment. He stated under oath that he paid her "in coordination with and at the direction of a candidate for federal office". Cohen was sentenced to three years in federal prison on various charges, and was disbarred.Daniels filed three lawsuits against Trump and/or Cohen. In the first lawsuit she argued that the NDA was invalid. She won the lawsuit, though it was dismissed after Trump and Cohen agreed not to enforce the NDA. A California court subsequently ordered Trump pay $44,100 to reimburse her legal fees. She lost the second lawsuit, in which she argued she was defamed, and was ordered to pay almost $300,000 in legal fees and court sanctions. In the third lawsuit she claimed that Cohen colluded with her previous attorney Keith Davidson against her interests when he negotiated the payment. The lawsuit did not name Trump as a defendant, and settled in May 2019.Trump's accounting firm, Mazars, provided his tax returns and related documents to the Manhattan District Attorney, Cyrus Vance Jr., following the outcome of the Supreme Court's Trump v. Vance ruling in February 2021. Although an internal report said there was "reason to believe" Trump's campaign had knowingly violated campaign finance law, the Federal Election Commission (FEC) abandoned an inquiry into the payment to Daniels. The FEC's vote on May 6, 2021, split 2–2 along party lines.On March 30, 2023, a Manhattan grand jury indicted Trump for his alleged role in the scandal. Trump was arraigned in the Manhattan district court on April 4.
