ST. LOUIS (AP) — Attorneys general in 20 conservative-led states are warning CVS and Walgreens that they could face legal consequences if they sell abortion pills by mail in those states. A letter Wednesday from Republican Missouri Attorney General Andrew Bailey to the nation’s largest pharmacy-dispensing companies was co-signed by 19 other attorneys general, warning that sale of abortion pills would violate federal law and abortion laws in many states. Missouri is among states that implemented strict abortion prohibitions last summer after the Supreme Court ruling overturning Roe v. Wade. Nineteen states have imposed restrictions on abortion pills, but there’s a court battle over whether they have the power to do so in defiance of U.S. Food and Drug Administration policy.
