Gov. Mary Fallin says Oklahoma will not develop health care exchange under Affordable Care Act

Gov. Mary Fallin rejected a proposal Monday to expand the Medicaid health care program to an estimated 150,000 uninsured individuals in Oklahoma and refused to establish an online marketplace for the uninsured to shop for health insurance.

For more than two years, a group of 28 states, mostly with Republican governors, have fought to prevent the implementation of the Patient Protection and Affordable Care Act, which has come to be known as Obamacare.

First, states challenged the law in federal court, but the Supreme Court upheld most of the law as constitutional in a ruling on a challenge led by Florida.

Now, many states are refusing to participate in two of the mandated programs.
