A Supreme Court decision striking down a majority Black congressional district in Louisiana has amplified an already intense national redistricting battle. The court's ruling Wednesday limits the use of race in drawing voting districts. In response, Louisiana Gov. Jeff Landry has suspended the state's May 16 congressional primary to allow time for state lawmakers to draw new House districts. Alabama Gov. Kay Ivey has called a special session to start Monday in case the Supreme Court allows the state to change its U.S. House districts. President Donald Trump also is urging Tennessee officials to redraw House districts to try to gain another seat for Republicans.
