Two poll workers were removed from their duties in Georgia's largest county on Tuesday.
Facebook posts surfaced showing the poll workers at the deadly January 6 riot at the US Capitol.
One post, shared with the Washington Post, read: "Mike Pence is a traitor."
The poll workers, a mother and son, were removed shortly before voting started.
Gabriel Sterling, the chief operating officer in the office of the Georgia Secretary of State, confirmed to CNN that the poll workers were removed.
