A Texas fight with a nurse practitioner may eventually push the Supreme Court to settle an intensifying battle between states with strict abortion-ban laws and those with shield laws to protect abortion providers supporting out-of-state patients. In a lawsuit filed Tuesday, Texas Attorney General Ken Paxton accused Debra Lynch, a Delaware-based nurse practitioner, of breaking Texas laws by shipping abortion pills that Lynch once estimated last January facilitated “up to 162 abortions per week” in the state. Fretting that Her Safe Harbor continues to advertise that Texas patients can get access to abortion pills “within days,” Paxton characterized Her Safe Harbor as an “extremist group” supposedly endangering women and unborn children in the state. But Lynch told The New York Times that her lawyers advised her to ignore the demand letter, because Delaware’s shield law is one of the strongest in the country. His lawsuit demands a temporary and permanent injunction shutting down Her Safe Harbor, as well as the highest possible fines.
