Timeline: Criminal probe into Trump's efforts to overturn Georgia election results

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.

Here's a look at how the probe — one of several investigations involving the former president — has unfolded so far.

Voters head to the polls in the 2020 general election.

Multiple media organizations, including ABC News, call the election for Joe Biden based on the projected electoral vote count, as several states, including Georgia, have yet to be projected.

The Trump campaign requests a hand recount in Georgia, where Biden leads by about 14,000 votes out of nearly 5 million cast in the presidential race.

Raffensperger, a Republican, announces that due to how slim the vote margin is between Biden and Trump, the state's planned audit will trigger a «full by-hand recount in each county» of the presidential race.

The results of Georgia's statewide audit, which entailed that counties recount by hand every vote cast in the presidential race, reaffirm Biden as the winner — by a margin of 12,284 votes. It's the first time since 1992 that a Democrat will win the state.

Georgia Gov. Brian Kemp and Raffensperger certify the results of the general election, making it official that Biden won the state's 16 electoral votes.

Georgia's 159 counties start counting the votes cast in the presidential race for a third time, after the Trump campaign requests a machine recount.
