ATLANTA — Fulton County District Attorney Fani Willis has asked county law enforcement to prepare for her impending plans to announce indictments this summer regarding interference in Georgia’s 2020 presidential election.

While Willis did not specifically say she plans to indict former President Donald J. Trump, the announcement comes on the heels of an investigation into Trump and some of his allies attempting to convince Georgia officials to overturn the state’s presidential election results.

In a letter to Fulton County Sheriff Patrick Labat, Willis said she plans to announce a charging decision sometime between July 11 to Sept. 1.

“I am providing this letter to bring to your attention the need for heightened security and preparedness in coming months due to this pending announcement,” Willis wrote.

On a recorded phone call with Secretary of State Brad Raffensperger after the 2020 general election, Trump can be heard pressing Raffensperger to “find” 11,870 votes, which would have given him the victory in Georgia, surpassing Joe Biden’s total.

Trump’s chief of staff at the time, Mark Meadows, called Raffensperger’s office at least 18 times to set up the call, according to information revealed at a June hearing by the House Select Committee investigating the Jan. 6 Capitol attack, which stemmed from Trump and his allies’s claims of election fraud.

In media interviews in February, the forewoman of the 26-member Fulton County Special Purpose Grand Jury —sanctioned last year to investigate possible criminal interference in Georgia’s election — hinted that the jury recommended indictments on several individuals.

The investigation also looked into the actions of more than a dozen Georgia Republicans who allegedly signed a certificate falsely declaring Trump as the winner of the election; and the alleged copying of data and software from election equipment in Coffee County by a computer forensics team hired by Trump allies.

Willis implied, though not referencing a specific event, in the letter to Labat that acts of violence have occurred in the past that go “outside of public expressions of opinion.” Most notably, Trump’s claims of election fraud ultimately resulted in his supporters attacking the U.S. Capitol Jan. 6, 2021 as Congress was preparing to certify the results of the 2020 election.

“Open-source intelligence indicated the announcement of decisions in this case may provoke a significant public reaction,” she said.

The letter, Willis said, was intended to provide sufficient time for the sheriff’s office to coordinate with local, state and federal agencies to ensure law enforcement is ready to protect the public when her charging decisions are announced.

Trump filed a motion March 20 seeking to quash the final report of the special purpose grand jury, which interviewed 75 witnesses. Trump’s motion also seeks to disqualify the Fulton County District Attorney’s office from any further investigations or potential prosecution for alleged interference.

Fulton County Superior Court Judge Robert McBurney ordered Willis respond to Trump’s motion by May 1.
