The Supreme Court has weakened a key tool of the Voting Rights Act that has helped root out racial discrimination in voting for more than half a century in a case concerning a Black majority congressional district in Louisiana.

As the U.S. Supreme Court hears a challenge to birthright citizenship, civil rights groups warn that weakening the 14th Amendment could put long-standing constitutional protections at risk and leave children stateless.
