Atlanta Mayor Keisha Lance Bottoms signed an order to “mitigate the impact of new voting restrictions imposed” by Georgia’s restrictive new voting laws.

Civil rights groups and businesses have spoken out against Georgia Republicans’ sweeping voter restrictions, which will disproportionately affect Black voters’ ability to cast their ballots.

It requires voters to submit ID information with both an absentee ballot request and the ballot itself. It limits the use of absentee ballot drop boxes, allows for unlimited challenges to a voter’s qualifications, cuts the runoff election period from nine to four weeks, and significantly shortens the amount of time voters have to request an absentee ballot.

The legislation also empowers the state legislature, currently dominated by Republicans, to appoint a majority of members on the five-person state election board. That provision would strip Georgia’s secretary of state, Brad Raffensperger, a Republican who stood up to Trump after the election, from his current role as chairman of the board. The bill creates a mechanism for the board to strip local election boards of their power.
