THE BAN: South Dakota’s Legislature approved a bill banning all abortions except those needed to save a woman’s life.

WHAT’S NEXT: Republican Gov. Mike Rounds is expected to sign the bill. Planned Parenthood has vowed to sue.

NATIONAL SIGNIFICANCE: The bill’s supporters ultimately hope to get the U.S. Supreme Court to overturn Roe v. Wade, the 1973 ruling establishing the right to an abortion.
