(CNSNews.com) - The American Life League is asking California Democratic Gov. Gray Davis to veto a bill that would require medical schools to train OB/GYN students how to perform abortions.

The bill passed the state Senate 25-13 earlier this month after getting approval from the Assembly by a 45-27 margin in May. Davis has yet to take a position on the bill.

In introducing the measure, Democratic Assemblywoman Hannah-Beth Jackson noted that most obstetrics and gynecology students must take elective classes if they want to receive abortion training.

Janice Rocco, Jackson's spokeswoman, said about 46 percent of OB/GYN residency programs provide training for abortions. Jackson's bill would make that training mandatory under most circumstances.

"We discovered this was a problem both in California and nationwide in terms of the percentage of residency programs that provide routine training in abortion services to their residents," Rocco said.

Judie Brown, president of the American Life League, said California would be the first state to take such a step. Earlier this year, New York City Mayor Michael Bloomberg required city-owned hospitals to provide abortion training for OB/GYN residency programs.

"The fact that anybody is required to learn how to kill a human being should be appalling to the average American," Brown said. "But we've forgotten as a nation that's what abortion does to people."

The bill would bring the state in line with the national Accreditation Council for Graduate Medical Education, which already requires abortion training for its accredited OB/GYN programs. Those guidelines provide an exemption for students and hospitals whose religious or moral objections would be in conflict.
