AUSTIN, Texas (AP) — A federal judge that will decide whether to block a Texas law that would end abortions at 18 clinics in Texas has pushed closing arguments to next week.

U.S. District Judge Lee Yeakel on Thursday heard the final witnesses in a four-day trial in Austin. The lawsuit was brought by abortion providers challenging a new law that would require their clinics to meet hospital-style operating standards by Sept. 1.
