Arizona's GOP Gov: Don't Defund Obamacare, We Need The Money

Arizona is one of several Republican-led states to accept the law's Medicaid expansion. The federal government covers 100 percent of the costs of the expansion for the first three years and never less than 90 percent after that. That funding is unaffected by the shutdown, but it would presumably be lost if the GOP actually succeeded in its push to defund the entire law.

If the state didn't receive that federal money, Brewer said, "we will be faced with a calamity."
