1. Gov. Kay Ivey of Alabama signed the nation’s most restrictive abortion law. It bans almost all abortions, with no exception in cases of rape or incest.

The law will go into effect in six months at the earliest. Lower courts will almost certainly block it.

There is no guarantee that the Supreme Court would hear an appeal, even though the law was constructed to be a direct challenge to the court’s landmark 1973 Roe v. Wade ruling.
