The Justice Department will file a federal lawsuit Friday against the state of Georgia for its efforts to enact new voting restrictions that federal authorities allege discriminate against Black Americans, according to people familiar with the matter.

The legal challenge takes aim at Georgia’s Election Integrity Act, which was passed in March by the Republican-led state legislature and signed into law by Gov. Brian Kemp (R). The law imposes new limits on the use of absentee ballots, makes it a crime for outside groups to provide food and water to voters waiting at polling stations, and hands greater control over election administration to the state legislature.

Attorney General Merrick Garland and Kristen Clarke, head of the Justice Department’s Civil Rights Division, will make the announcement later Friday alongside others who worked closely on developing the lawsuit, including Associate Attorney General Vanita Gupta and Principal Deputy Assistant Pamela Karlan, the people familiar with the matter said. They spoke on the condition of anonymity because the action has not been formally made public.

Lawmakers on Capitol Hill have been briefed on the matter.

The action is the first major voting rights case the Justice Department has filed under the Biden administration and comes as Republican-led state governments across the country have been seeking to impose broad new voting restrictions in the wake of President Biden’s victory over Donald Trump last November. Trump has spent months waging a baseless effort to discredit the result, making false and untrue allegations of widespread voter fraud.
