Wisconsin Gov. Scott Walker is pushing a plan to make his state the first to drug-test adults applying for food stamps, a plan that courts have shot down as unconstitutional, according to a report Tuesday.

Walker, a Republican, has resurrected a measure approved by the GOP-controlled Legislature two years ago but has sat dormant because it violates federal rules about imposing extra eligibility requirements for food stamps recipients, the Minneapolis Star Tribune reported.

A federal appeals court in 2014 shot down Florida’s attempt to drug-test recipients, saying it violates the constitutional protections against unreasonable searches.

Walker, a presidential candidate in 2016, approved a rule change to implement the testing and forwarded it to the Legislature for review, the newspaper reported.
