MADISON, Wis. (AP) — An obstetrician is testifying that an abortion provider abandoned a patient who needed a hysterectomy as state attorneys try to persuade a federal judge to uphold Wisconsin's law requiring abortion providers get hospital admitting privileges. Milwaukee-based obstetrician James Linn testified Wednesday that several years ago he assisted on a hysterectomy on a woman who suffered a lacerated uterus during an abortion. He says his colleague tried to reach the doctor who performed the abortion but the provider never called back. He says in his mind the provider abandoned the patient. Linn's testimony comes as part of a federal lawsuit Planned Parenthood and Affiliated Medical Services filed last year challenging the admitting privileges mandate. State attorneys contend the requirement ensures continuity of care.
