Louisiana Gov. Jeff Landry (R) told Republican House candidates Wednesday that he plans to suspend next month’s primary elections so state lawmakers can pass a new congressional map first, according to two people with knowledge of the calls.

The move follows a Supreme Court decision earlier in the day that found Louisiana had unlawfully discriminated by race when it created a second majority Black congressional district under legal pressure. The ruling positions Republicans to gain one or two seats in the midterms as they fight to hold their narrow majority in the House.

The 6-3 decision limited a key provision of the landmark Voting Rights Act and could lead to other Black Democrats across the South losing their House seats. Most states are unlikely to be able to redraw districts in time for the November midterm elections, but Louisiana could be one of the exceptions.

Landry’s announcement to suspend the May 16 primary could come as early as Friday — one day before early voting is to begin, according to people familiar with his plans who spoke on the condition of anonymity to discuss private conversations.

Election officials sent ballots to overseas voters weeks ago. It’s unclear whether the governor’s suspension would apply only to primaries for the six House seats, or include other elections, including the heated Senate primary that pits incumbent Sen. Bill Cassidy (R) against Rep. Julia Letlow (R). Louisiana has six House seats, two of which are held by Democrats.
