With signs mounting that prosecutors are moving closer to indicting Trump, the 76-year-old billionaire took to his Truth Social platform on Saturday morning, saying: "Leading Republican candidate & former President of the United States of America will be arrested on Tuesday of next week. Protest, take our nation back!"
Trump chose to use his own social media platform to make the announcement, despite being reinstated on Facebook and YouTube on Friday, more than two years after he was banned over the US Capitol riot.
The investigation, led by Manhattan district attorney Alvin Bragg, an elected Democrat, centers on $130,000 paid weeks before the 2016 polls to stop Stormy Daniels, whose real name is Stephanie Clifford, from going public about an affair she says she had with Trump years earlier.
If Trump were indicted, the 76-year-old would become the first former president to be charged with a crime. That would also send political shock waves as Trump tries to secure the Republican nomination for the 2024 presidential election.
Trump's lawyer told CNBC on Friday evening that his client would surrender to face criminal charges if he was indicted.
Trump has denied having an affair with Daniels and has dismissed the investigation as politically motivated.
In his Truth Social post, written in capital letters, Trump referred to "illegal leaks from a corrupt & highly political Manhattan district attorneys office" and said the investigation was "based on an old & fully debunked (by numerous other prosecutors!) fairytale."
Facebook and YouTube, where Trump has millions of followers, benched him days after a mob of his supporters stormed Congress on January 6, 2021, arguing that his posts incited unrest.
A grand jury in New York, a citizen panel which examines evidence presented by prosecutors to decide if a charge is warranted, has been hearing from witnesses in Trump's case.
On Monday, they heard from Trump's former lawyer and fixer Michael Cohen, who made the payment to Daniels. Cohen was sentenced to three years in prison in 2018 on federal charges related to the payment. He pleaded guilty but said he had been carrying out Trump's orders.
Daniels herself met with prosecutors on Wednesday and "agreed to make herself available as a witness, or for further inquiry if needed," according to her lawyer Charles Brewster.
Trump has also received an invitation to testify, which legal experts say is a sign that an indictment is near.
The payment to Daniels, if not properly accounted for, could result in a misdemeanor charge related to falsifying of business records. That might be raised to a felony if the false accounting was intended to cover up a second crime, such as a campaign finance violation, The New York Times has reported.
Trump is facing several criminal probes at state and federal level over possible wrongdoing before, during and after his term in office that threaten his new run at the White House.
In Georgia, a prosecutor is investigating Trump and his allies' efforts to overturn his 2020 election loss in the southern state. The grand jury in that case has recommended multiple indictments, the forewoman revealed last month.
The former president is also the subject of a federal probe into his handling of classified documents as well as his possible involvement in the January 6, 2021, assault on the US Capitol.
Some observers believe an indictment bodes ill for Trump's 2024 chances, while others speculate that it could on the contrary serve as a huge boost.
"The arrest secures the nomination for Donald Trump," tweeted Rick Wilson, a political strategist who quit the Republican Party in protest over Trump. "The base will rally politically, and possibly physically. (Let me know how that goes.)"
Trump called a new campaign rally in Texas on March 25.
