HELENA, Mont -

The U.S. Supreme Court's decision to uphold the federal health care law means state officials will continue working to implement it.

Montana insurance commissioner Monica Lindeen says the state will help the U.S. Department of Health and Human Services establish Montana's health insurance exchange, since the Republican-led Montana legislature last year rejected a plan for Montana to design its own.

The insurance exchanges will be a place for about 18 percent of Montanans who are uninsured to buy coverage from private insurers with the help of up-front federal tax credits.

Attorney General Steve Bullock says the high court's decision on Thursday shows the lawsuit against the law was a waste of money, vindicating his decision to keep Montana out of it.
