Texas Attorney General Ken Paxton on Monday asked a court to make a New York county enforce a $100,000 judgment against a doctor for sending abortion pills to Texas, taking an unprecedented interstate conflict to court.

Texas has not banned abortion pills entirely, and the Supreme Court has previously upheld access to those medications when parties have sued the Food and Drug Administration. A ban stalled in the Texas House earlier this year.

Ken Paxton has been requesting a judgment on Dr. Margaret Carpenter, who prescribed abortion pills to patients in Texas despite not having a license there.
