A Texas doctor who publicly said he performed an abortion was sued Monday in state court by two different plaintiffs, handing Texas the first tests of its new abortion law. The Texas law bans abortions after about six weeks of gestation when a fetal heartbeat can be detected, and it deputizes private citizens to sue anyone they believe may have aided such a procedure and collect $10,000. It went into effect Sept. 1. Alan Braid, a San Antonio physician, said in a Washington Post opinion essay Saturday that he had performed an abortion in defiance of the law earlier this month.
