Federal Judge Strikes Down Abortion Med, Sowing Chaos Nationwide

States and abortion rights advocates vow to fight a federal judge's ruling effectively banning the abortion drug mifepristone.
Pharmaceutical companies warn the ruling undermines FDA authority and endangers medical innovation.
Access to mifepristone remains unchanged in states supporting the FDA's approval but is set to be cut off elsewhere.
The issue appears headed for the Supreme Court, where the conservative majority last year revoked the constitutional right to abortion.
