Sources at the secretary of state’s office say an email that Wood sent to Gray caused them to launch an official investigation.

In the email, Wood confirmed he moved to South Carolina, writing “I have been domiciled in South Carolina for several months after purchasing property in the state in April.”

Now state election investigators are looking into whether that means Wood legally should not have been able to vote in the November election.

They cite a section of Georgia code that reads, “If a person removes to another state with the intention of making it such person’s residence, such person shall be considered to have lost such person’s residence in this state.”
