Former President Donald Trump and some Republicans have had concerns about noncitizens voting in the presidential election, and a battleground state is doing something about it.

Georgia is posting signs at polling places warning noncitizens that they could be prosecuted if they vote, Just The News reported.

The former president was barely defeated in the state in 2020 and his phone call to Secretary of State Brad Raffensperger was the basis of a criminal case against him by Fulton County District Attorney Fani Willis.

The former president and Secretary of State have been at odds since that election but it is Raffensperger who had the signs placed at the state’s 2,400 polling locations in English and Spanish.

“Only United States citizens may vote in Georgia,” the signs say.
