A judge in the US state of Georgia has released parts of a grand jury report on former president Donald Trump's attempts to overturn his 2020 election defeat in the state, though the specific recommendations on criminal charges remain sealed.

On Monday, Fulton County Superior Court Judge Robert McBurney had said that he would permit three portions of the special grand jury's report to be released: the introduction, the conclusion and a section laying out concerns that some witnesses may have lied under oath.

Judge McBurney said the report, parts of which were released online by Fulton County today, includes "a roster of who should (or should not) be indicted".

But the judge ruled those details would stay secret for now out of concern that people named have not had an adequate opportunity to defend themselves.

Fulton County District Attorney Fani Willis opened an investigation shortly after Mr Trump - in January 2021 - called a Georgia state official asking him to "find" just enough votes to declare the Republican incumbent the winner in the state rather than Democrat Joe Biden.

Mr Trump, who has launched another run for the White House in 2024, has made false claims that the 2020 election was stolen from him through widespread voting fraud. He has denied wrongdoing and accused Ms Willis of targeting him for political reasons.

The Georgia investigation is one of several threatening Mr Trump, including separate US Justice Department inquiries into his retention of classified materials after leaving office as well as his efforts to invalidate the 2020 election results.

The special grand jury had subpoena power, which it used to secure sworn testimony from his close allies such as lawyer Rudy Giuliani and Republican Senator Lindsey Graham as well as top Georgia officials including Republican Governor Brian Kemp.

It was not empowered to issue indictments, only recommendations, and the decision on whether to press charges ultimately rests with Ms Willis, the district attorney. If she decides prosecution is warranted, she would need to pursue indictments from a regular grand jury.

At a court hearing last month on whether to release the report, Ms Willis said charging decisions were "imminent".

Mr Trump called Georgia's top election official, Brad Raffensperger on 2 January 2021, and claimed falsely that the election results were fraudulent. A recording of the call was leaked.

"I just want to find 11,780 votes, which is one more than we have, because we won the state," said the former president, referring to the margin of 11,779 votes by which Mr Biden won.

Four days later, a group of Trump supporters stormed the US Capitol in a failed bid to stop Congress from certifying President Biden's victory.

Ms Willis has also examined a scheme in which a slate of alternate electors falsely asserted that Mr Trump had won Georgia in an unsuccessful effort to award the state's electoral votes to him rather than Mr Biden.
