Texas has sued a New York doctor for prescribing abortion pills to a Texas woman via telemedicine. It appears to be the first challenge in the U.S. to a state shield law that’s intended to protect prescribers in Democratic-controlled states from being punished by states with abortion bans. Prescriptions like these, made online and over the phone, are a key reason that the number of abortions has increased across the U.S. even after state bans started taking effect. Most abortions in the U.S. involve pills rather than procedures. Anti-abortion groups are increasingly focusing on the rise of pills.
