Georgia Secretary of State and Republican gubernatorial candidate Brian Kemp received a voter card that said “invalid” when he tried to vote on Election Day.

Kemp, who went to his home polling place in Winterville, Ga., on Tuesday afternoon, had to go back and get another card after unsuccessfully trying to vote, according to Atlanta’s ABC affiliate, Channel 2 Action News.

A Kemp aide told The Hill that a poll worker was able to right the issue quickly, and his voting experience was “smooth.”

{mosads}Kemp is not the only Georgia voter to encounter issues casting a ballot. Many voters reported long wait times and malfunctioning voting machines at some of the state’s polling sites. One location mistakenly installed only three voting machines where there should have been one voting machine to every 350 voters registered in that precinct.

The closely watched race between Kemp and Democrat Stacey Abrams for the state’s highest office has become increasingly heated in recent months.

Abrams has accused Kemp of voter suppression efforts, while many have challenged the legitimacy of Kemp presiding over the very race he’s trying to win. Kemp has faced a number of lawsuits related to the state’s voter registration laws over concerns about suppression of minority voters.

Kemp is also facing calls to recuse himself from presiding over the race. A nonprofit filed an emergency lawsuit late Tuesday seeking to block him from counting votes or certifying results in his capacity as secretary of state.

Abrams cast her vote early, according to Channel 2. Early voting in the state shattered previous records, with more than 2 million people casting ballots. Abrams would be the first black female governor in the U.S. if she wins.

The Hill has reached out to the Athens-Clarke County Board of Elections for comment.
