Wisconsin Attorney General J.B. Van Hollen says Gov. Scott Walker must follow the federal health care law.
The U.S. Supreme Court found the law constitutional on Thursday, but Walker, a Republican, has vowed not to implement it until after the November elections. The governor hopes the next president and Congress will repeal the law.
Nearly 30 states, including Wisconsin, sued over the law, alleging it was unconstitutional. Van Hollen, a Republican, handled Wisconsin's participation in the lawsuit.
But he said Thursday that Walker is obligated to follow the law according to its deadlines.
Asked at a news conference whether he was obligated to conform to the law, Walker responded by saying the legislation establishes multiple timelines.
