An Oklahoma doctor is suing in hopes of blocking a new law that imposes stricter regulations on abortion providers.
The Center for Reproductive Rights filed the lawsuit Thursday on behalf of Dr. Larry Burns, who the center says performs nearly half the state's abortions.
The lawsuit aims to block a law that would require clinics to have a physician with admitting privileges at a nearby hospital present when an abortion is performed. It would take effect Nov. 1.
A similar law is being challenged in Texas.
