JACKSON, Miss. (AP) -- A federal judge will hear arguments Wednesday about whether to extend his temporary block of a law that could close Mississippi's only abortion clinic.

The law would require anyone doing abortions at the Jackson Women's Health Organization clinic to be an OB-GYN with privileges to admit patients to a local hospital.

The clinic says it has been unable to obtain admitting privileges for its two out-of-state physicians. It also argues in court papers that the requirement "gives hospitals a third-party veto over the availability of abortion in Mississippi."

State attorneys argue the requirement is designed for patient safety.

U.S. District Judge Daniel P. Jordan (JERR-dun) III temporarily blocked the law July 1, the day it was to take effect.
