WASHINGTON (AP) — Justice Ketanji Brown Jackson said Monday that the Supreme Court risks being seen as political in the wake of a major voting rights decision.

She spoke after writing a solo dissent from the court’s decision allowing Louisiana to move quickly to use new maps after the court’s conservative majority struck down a majority-Black district and weakened the Voting Rights Act.

“Public confidence is really all the judiciary has,” she said at a talk before the American Law Institute in Washington, D.C.

“Everyone believes the court system is outside the political sphere. I think that means it’s incumbent on us to do things, to act in ways, that shore up public confidence,” she said.
