Black residents in a newly created Louisiana congressional district fear they could lose their representation under a case being heard before the U.S. Supreme Court.

Residents of the 6th Congressional District say they now feel better represented with last year's election of U.S. Rep. Cleo Fields, a Black Democrat who was able to win after a newly drawn political map carved out a second Black majority congressional district in the state.

The district was drawn as part of a lawsuit that alleged Louisiana Republicans had disenfranchised Black voters by drawing just one majority minority district out of six in a state where the population is one-third Black.

But opponents of the second Black majority district argue it was the result of an illegal gerrymander based on race.

The court hears arguments Wednesday.

The court's decision could have wide-ranging consequences for the Voting Rights Act.
