WICHITA, Kan. (AP) _ A Wichita doctor is seeking to quash or modify the subpoena filed by an abortion opponent accused of sending a threatening letter after learning of the doctor's plans to offer abortions.

The dispute comes in the civil lawsuit filed by the Justice Department against anti-abortion activist Angel Dillard, of Valley Center, under a federal law protecting access to reproductive services.

Dr. Mila Means argued Thursday the subpoena seeking documents for her deposition next week are overly broad and burdensome. She also contends the subpoenaed information about her efforts to obtain funding or a facility to provide abortions could subject others to threats and intrusions by abortion opponents.

No abortions have been performed openly in Wichita since Dr. George Tiller was shot to death at his church in May 2009.
