Louisiana already has suspended its May 16 congressional primary to allow time for lawmakers to approve new U.S. House districts, though that is being challenged in court. Meanwhile, President Donald Trump is pressuring other states such as Tennessee to also redistrict ahead of the midterm elections that will determine whether Republicans maintain control of the closely divided House.

Trump urged Texas Republicans last year to redraw U.S. House districts to give the party an advantage. Democrats in California responded by doing the same. Then other states joined the battle. Lawmakers, commissions or courts have adopted new House districts in eight states.

That total could grow following the Supreme Court's decision that significantly weakened a provision in the federal Voting Rights Act.

Here's a look at how some states are responding to the Supreme Court ruling:

Louisiana

Early in-person voting was to begin Saturday for Louisiana's primaries. But Republican Gov. Jeff Landry moved quickly Thursday to postpone the congressional primary while allowing elections for other offices to go forward.

A federal lawsuit filed later Thursday, on behalf of a Democratic congressional candidate and voter, asked a court to block Landry's order and allow the House primary to occur as originally scheduled. Two more lawsuits asserting that the congressional primary should go forward were filed Friday in state court on behalf of voters who already had cast absentee ballots and several civil rights organizations.

Among other things, the lawsuits contend that Landry lacked authority to suspend the primary and that thousands of absentee ballots already have been mailed to people, with a substantial number filled out and returned.

Separately, a three-judge federal court panel that heard the case that was appealed to the Supreme Court also issued an order Thursday suspending Louisiana's congressional primary.

Republican state House and Senate leaders said they are prepared to pass new U.S. House districts — and set a new primary election date — before their legislative session ends in a month.

Alabama

The state's primaries are set for May 19. But Alabama officials on Thursday filed an emergency motion with the Supreme Court seeking an expedited review of a pending appeal in a redistricting case that could affect the election.

A federal court in 2023 ordered the creation of a new near-majority Black district in Alabama, resulting in the election of a second Black representative to the U.S. House. Alabama is under a court order to use the new map until after the next census in 2030.

An appeal pending before the Supreme Court argues that the map is an illegal racial gerrymander, a claim similar to that made in Louisiana.

The state is seeking to lift an injunction blocking the use of a 2023 map drawn by the Republican-controlled Legislature that did not include the new district. The state is making a similar request for two state Senate districts impacted by a separate redistricting case.

Ivey said the special legislative session will focus on a contingency plan to have special primary elections in case the Supreme Court acts quickly enough to allow Alabama's previously drawn districts to be used this year.

Florida

Hours after the Supreme Court's decision, Florida's Republican-led Legislature approved new U.S. House districts that could help the GOP win up to four additional seats in November.

Republican Gov. Ron DeSantis called a special legislative session without knowing when the Supreme Court would issue its opinion in the Louisiana case. But DeSantis expressed confidence that the court would rule as it did. Among other things, the new map reshapes a southeastern Florida district that DeSantis said was created to help elect a Black representative in an attempt to comply with the federal Voting Rights Act.

A Florida constitutional amendment approved by voters in 2010 prohibits districts from being drawn to deny or diminish the ability of racial or language minorities to elect the representatives of their choice. DeSantis said he considers that amendment a violation of the U.S. Constitution. That question is expected to be decided by the courts.

Tennessee

The Tennessee General Assembly recently ended its annual session. But pressure is growing to bring lawmakers back to revise the state's congressional districts.

Trump posted on social media Thursday that he had spoken with Republican Gov. Bill Lee, who he said would work hard for a new map that could help Republicans gain an additional seat. Democrats currently hold only one seat, a district centered in Memphis, which is majority Black.

Tennessee House Speaker Cameron Sexton, a Republican, said he is in conversations with the White House and others while reviewing the court's decision.

The state's candidate qualifying period ended in March. The primary election is scheduled for Aug. 6.

Mississippi

Mississippi held its U.S. House primaries in March. But the Supreme Court's decision could affect elections for other offices.

Republican Gov. Tate Reeves announced previously that he would call a special legislative session to redraw voting districts for the state Supreme Court that would begin 21 days after the U.S. Supreme Court ruled in the Louisiana case. That would put the special session's start at around May 20.

A federal judge last year ordered Mississippi to redraw its Supreme Court voting districts after finding that they violated the Voting Rights Act by diluting the power of Black voters. Mississippi lawmakers had been waiting on a decision in the Louisiana case before moving forward, but their legislative session ended in April.

Reeves said in his proclamation that the Supreme Court's decision would provide guidance to lawmakers on whether "race-conscious redistricting" violates the U.S. Constitution.

Georgia

Early in-person voting began April 27 and continues for the next few weeks ahead of Georgia's primary elections on May 19.

Republican Gov. Brian Kemp said it's too late for Georgia officials to try to change congressional districts for this year's elections, because voting already is underway. But he said the rationale in the Supreme Court's decision "requires Georgia to adopt new electoral maps before the 2028 election cycle."
