A coalition of voting rights groups on Wednesday denounced election officials in Hall County, Georgia, for opening fewer early voting sites, which the groups say is limiting turnout of Black and Latino voters during crucial January runoff elections that will determine control of the U.S. Senate .

Officials in the county, which is located about an hour northeast of Atlanta, opened four polling locations when early voting in the runoffs began Dec. 14. Thats down from eight early voting locations for the November elections.

The two Jan. 5 contests pit Republican Sens. David Perdue and Kelly Loeffler against Democrats Jon Ossoff and Rev. Raphael Warnock , respectively.

During a Wednesday conference call hosted by several prominent national and Georgia-based Latino groups, activists said that the closures are concentrated in the countys Latino and Black communities.

This is what voter suppression looks like, said Tania Unzueta of the MiJente Support Committee, a national Latino voting rights advocacy group. This is one example of what we dont want to happen, particularly in an important runoff.
