PHILADELPHIA -

A Philadelphia abortion provider serving life in prison for murder has rejected a plea deal in a federal drug case.

Dr. Kermit Gosnell had been expected to plead guilty Wednesday to charges that he illegally distributed painkillers.

Instead, Gosnell rejected the deal with prosecutors. It would have tacked on a 20-year sentence to the life term he's currently serving.

Prosecutors said Gosnell, 72, ran a "pill mill" by day and a rogue "abortion mill" by night at a filthy clinic in West Philadelphia.

Gosnell was convicted in May in the deaths of three babies born alive at his clinic.

The judge set a trial date of Sept. 9 on the drug charges.
