Georgia's Republican-controlled state election board may vote on Friday to require a labor-intensive hand count of potentially millions of ballots in November's election, a move voting rights advocates say could cause delays,

One measure, to be voted on Friday, would require hand counting of ballots. Critics say that it would create widespread confusion in a state pivotal to the presidential race.

Georgia election officials have said they are “gravely concerned that dramatic changes” approved by the State Election Board “will disrupt the preparation and training processes already in motion.”

The office of Georgia Attorney General Chris Carr sent a letter to the members of Georgia’s State Election Board Friday morning telling them some of the planned rule changes to election policies ahead of the presidential race may violate state law.
