ATLANTA (AP) — Gov. Brian Kemp signed legislation Tuesday that makes additional changes to Georgia’s election laws ahead of the 2024 presidential contest in the battleground state, including defining probable causes for removing voters from the rolls when their eligibility is challenged.

Republican activists — fueled by debunked theories of a stolen election — have challenged more than 100,000 voters in the state in recent years. The activists say they are rooting out duplicate records and removing voters who have moved out of state.

The bill Kemp signed into law — SB 189 — lists death, evidence of voting or registering in another jurisdiction, a tax exemption indicating a primary residence elsewhere, or a nonresidential address as probable causes for removing voters from the rolls. Most controversially, it says the National Change of Address list can be considered, though not exclusively.
