Former US president Donald Trump said on Tuesday that he would release a detailed report next Monday on what he called "election fraud" in the state of Georgia in 2020.
Mr Trump made the announcement in a post on his Truth Social media app.
Since his defeat in 2020, Mr Trump has repeatedly made false claims that the election was marred by widespread fraud. Those claims have been rejected by courts, state reviews and members of his own administration.
Mr Trump and 18 allies have been indicted in Georgia with scheming to overturn his 2020 election loss in the state.
Prosecutors turned to a statute normally associated with mobsters to accuse the former president, lawyers and other top aides in a sweeping criminal conspiracy aimed at keeping him in power.
The 97-page indictment details dozens of acts by Mr Trump and his allies to undo his defeat in the battleground state, including hectoring Georgia’s Republican secretary of state to find enough votes to keep him in power, pestering officials with bogus claims of voter fraud and attempting to persuade Georgia politicians to ignore the will of voters and appoint a new slate of electoral college electors favourable to Mr Trump.
It also outlines a scheme to tamper with voting machines in one Georgia county and steal data.
“Trump and the other defendants charged in this indictment refused to accept that Trump lost, and they knowingly and wilfully joined conspiracy to unlawfully change the outcome of the election in favour of Trump,” said the indictment issued by the office of Fulton County district attorney Fani Willis.
Other defendants include former White House chief of staff Mark Meadows, Mr Trump’s personal attorney Rudy Giuliani and a Trump administration Justice Department official, Jeffrey Clark, who advanced his efforts to undo his election loss in Georgia.
