A new filing from the Fulton County District Attorney’s office paints the clearest picture yet of the scope of a special grand jury’s investigation into potential election interference in Georgia’s 2020 presidential election by former President Donald Trump and his allies.

The Tuesday response to Gov. Brian Kemp’s motion to quash his closed-door testimony in the probe outlines potential lines of questioning for the governor and hints that the wide-reaching investigation will likely not finish before the November midterm election…..

But the most revealing part of the DA’s filing is a section that notes why the governor is a key witness to the ongoing probe into potential criminal election interference, including Trump’s previous statements about unsubstantiated claims of voter fraud and calls he made to Kemp to convene a special legislative session to reverse the election.

Kemp was one of a small but powerful group of Republican officials that did not promote false claims about the 2020 election and certified the results that saw President Joe Biden narrowly win Georgia’s 16 electoral votes.

The special grand jury appears to be interested in the relationship between pressure Kemp faced post-election from Trump and others and the pressure Secretary of State Brad Raffensperger received, including the infamous call between Trump and Raffensperger where the state’s top election official was asked to “find” votes to change the outcome of the already-certified election.

“Consequently, before the grand jury, [Kemp] can testify about any factual connections between the telephone calls to Secretary Raffensperger and telephone calls concerning relief being sought from [Kemp],” Wade wrote.
