The Supreme Court agreed to consider a major rollback of abortion rights.
The bench says it will take up Mississippi's bid to enforce a 15-week ban on abortion.
The court will hear the case this fall, with a decision likely to come down next summer.
Mississippi passed a law in 2018 that bans abortions after 15 weeks except in some situations, but the law was blocked by a federal appeals court.
The court's 1973 Roe v. Wade decision allows women the right to an abortion.
