Trump indictment updates: Former president to hold press conference on Georgia

Journalist George Chidi, who previously said he was asked to come before the Fulton County grand jury to testify on Tuesday, now says his testimony has been moved up and he has been asked to come in Monday.

In a post on X, formerly known as Twitter, Chidi said there was a "change of plans."

"They're moving faster than they thought," he wrote.

Chidi previously said he was present as a reporter in December 2020 at the Georgia state Capitol, where a slate of so-called "alternate electors" were allegedly meeting as part of a plan that prosecutors have said was intended to keep Joe Biden from amassing 270 electoral votes when the votes were certified on Jan. 6.

Former President Donald Trump on Monday launched a string of familiar attacks against Fulton County District Attorney Fani Willis on Monday as Willis is expected to begin presenting her election interference case to a grand jury later today.

In three all-caps posts on his social media platform Truth Social, Trump attacked Willis over her investigation, blasted media leaks, specifically urged "someone" to tell the grand jury he did not interfere in the election while continuing to make false claims that the 2020 election was stolen.

On Jan. 2, 2021, former President Donald Trump asked Georgia Secretary of State Brad Raffensperger to "find" the votes needed to win the state in the 2020 election.

The now-infamous phone call helped spark a criminal investigation launched the following month by Fulton County District Attorney Fani Willis looking into the efforts by Trump and his allies to overturn the results of the 2020 election.

Who are the key players in the criminal probe into former President Donald Trump's alleged election interference?

Some are local officials, including Georgia Secretary of State Brad Raffensperger, who certified the state's election results, and District Attorney Fani Willis, who is expected to bring the case before a grand jury as soon as Monday.

Others were working with Trump during or after the election, including his former lawyers Rudy Giuliani and John Eastman, both of whom appeared before a special grand jury.
