LEAVENWORTH, Kan. (AP) - A preliminary hearing has been delayed for a former physician assistant accused of sexually abusing patients at a Department of Veterans Affairs hospital in Leavenworth.

Mark Wisner's hearing on a charge of aggravated sexual battery was scheduled for Thursday but it was continued until Sept. 15.

The Leavenworth Times reports Wisner also is charged in a second case. He's charged with aggravated criminal sodomy and three misdemeanor charges of sexual battery. Those crimes allegedly occurred in 2014 while Wisner worked at the Eisenhower VA Medical Center.

Wisner's attorney, John Bryant, asked for the continuance for the first case because he is having difficulty meeting with his client.

Wisner surrendered his medical license after at least seven patients accused him of abusing them.
