Gov. Scott Walker is following through on his campaign promise to require drug testing for public aid recipients in Wisconsin and limiting how long they can receive benefits.

The potential 2016 Republican presidential candidate on Thursday announced more details about those plans that he first proposed during last year's campaign. The drug-testing requirements and benefits restrictions will be included in his two-year budget proposal being released on Feb. 3.

Walker is proposing that drug testing be required for those applying for or receiving benefits from a variety of state aid, including unemployment insurance and FoodShare, which is Wisconsin's food stamp program.

Walker says those who fail the drug test will be given the opportunity to participate in a free drug-testing program and receive job training.
