JANESVILLE, Wis. (AP) -

A Wisconsin district attorney has stopped allowing veterans to enroll in a court program designed for them, saying it's costly and doesn't meet national standards.

The Veterans Treatment Court was set up in 2009 to help service members charged with drug and alcohol violations, along with other crimes. Defendants get treatment through the Department of Veterans Affairs and can see charges reduced or dismissed if they successfully finish the program.

Thirty veterans have participated in the program, including 11 who are still enrolled.

But Rock County District Attorney David O'Leary has told his staff to stop accepting people into the program. He says one concern is that drug tests aren't as frequent as they should be. He tells the Janesville Gazette the problem also eats up staff time.
