Updating with Gov. Brian Kemp’s response:
The 2020 election in Georgia was not stolen.
For nearly three years now, anyone with evidence of fraud has failed to come forward - under oath - and prove anything in a court of law. Our elections in Georgia are secure, accessible, and fair and will continue to be as long as I am governor.
The future of our country is at stake in 2024 and that must be our focus.
If you scope it all the way down to something miniscule then yes, but it’s not possible to prove negatives more generally.
Proving non-existence of a divine entity for instance.
