An arrest warrant has been issued for a New York doctor indicted on Friday by a Louisiana grand jury for allegedly prescribing abortion pills online to a pregnant minor in the Deep South state, which has one of the strictest near-total abortion bans in the country.

A New York doctor was indicted by a grand jury in West Baton Rouge, Louisiana, on Friday for prescribing an abortion pill that was taken by a teenager there.

The case is one of the first direct challenges to shield laws enacted in blue states that protect providers who prescribe abortion pills to out-of-state patients.
