LEAVENWORTH, Kan. -- An Army veteran and his wife have filed a federal lawsuit, the ninth such suit aimed at allegations a VA Medical Center physician assistant sexually abused veterans at the Eisenhower VA Medical Center in Leavenworth.

The unnamed plaintiffs claim the Army helicopter crew chief became a patient of Wisner's as he recovered from a chopper crash. The veteran and his wife allege he was sexually abused, that the VA knew Wisner had a history of such abuse and did nothing, and that the VA failed to turn up a 1987 San Bernardino, California citation for lewd solicitation in an adult book store.

Our FOX 4 News investigation into Wisner and the VA turned up that citation.

Other veterans have either filed lawsuits or Federal Tort Claims Act claims, which are required before a lawsuit can be filed against the government. Wisner and the Secretary of the VA are also named in the lawsuits. Those lawsuits make similar claims against the government and Wisner.

Wisner abruptly resigned from the position in Leavenworth last year, and surrendered his license. He also faces two felony and two misdemeanor sexual abuse counts involving veteran patients in Leavenworth County.

The VA has chosen not to comment on the specifics of the lawsuits, but has referred to comments made by VA Secretary Robert McDonald in a visit to Leavenworth earlier this year.

When asked about allegations against Wisner McDonald said he was pleased the VA acted quickly to remove Wisner from patient care, and that patient safety is of the utmost importance.
