The U.S. Supreme Court cleared the way Monday for Alabama to eliminate one of its two majority-Black congressional districts ahead of November’s midterm elections. The move could hand Republicans an additional House seat. Alabama is one of several Republican-led states rushing to redraw maps and disenfranchise Black voters after the Supreme Court gutted a key Voting Rights Act provision last month.

Meanwhile, Virginia Democrats on Monday asked the U.S. Supreme Court to restore a voter-approved congressional map struck down by Virginia’s high court last week. The new Virginia districts could help Democrats secure up to four seats in the House.
