Former US President Donald Trump has been charged with conspiring to overturn his loss in the 2020 election. He is charged with four counts, including conspiracy to defraud the US, tampering with a witness and conspiracy against civil rights.
The indictment includes an investigation into events related to the January 6, 2021 riots at the US Capitol.
Trump, who is running for president again, denies the allegations. On social networks, he called the case "ridiculous".
"They want another false indictment against me a day after the Joe Biden scandal, one of the biggest in American history, broke out in Congress," he wrote on social networks.
The Republican politician has been charged in two other cases: mishandling classified files and falsifying business records to cover a payment to porn star Stormy Daniels.
The election investigation has focused on Mr Trump's actions in the two-month period between his loss to Joe Biden and riots in Washington DC, where his supporters stormed Congress as lawmakers certified the Democrat's victory.
Special Counsel Jack Smith, who led the investigation, said: “The attack on our nation's capital on January 6, 2021 was an unprecedented attack on the seat of American democracy. As described in the indictment, it was fed by lies."
Smith concluded his brief statement by vowing to seek "a speedy trial," while stressing that the former president "must be presumed innocent until proven guilty."
Trump will appear in court Thursday in Washington, DC. The 45-page indictment lists six unnamed associates: four lawyers, a Justice Department official and a political consultant.
The court document accuses Mr Trump of a "conspiracy to impair, obstruct and defeat the function of the federal government through dishonesty, fraud and deceit".
