State leaders are positioning themselves to have a key voice in a potential rewrite of ObamaCare next year.

With the election of Donald Trump, Republican leaders in Congress have promised a dramatic overhaul of President Obama’s signature policy.

The National Governors Association (NGA), a proudly bipartisan group representing every state, is now eyeing a more public — and more aggressive — role alongside GOP leaders as they attempt to gut the massive federal program.

New York may have misallocated roughly $150 million in Obamacare grants, the Department of Health and Human Services Office of the Inspector General said Tuesday. The watchdog office says the state should refund any misspent money to the federal government.

HHS OIG found the state did not have internal procedures necessary to ensure federal funding was allocated properly to set up the state’s Affordable Care Act insurance exchange.

A new study by Jonathan Gruber, one of the ACA’s chief architects, suggests that roughly two-thirds of new Medicaid enrollees in 2014 were eligible for the program under previous state eligibility criteria—meaning that they were not made eligible by the ACA. Gruber’s results, combined with much higher than expected Medicaid enrollment and spending over the past three years, has profound implications for the distribution of program costs and the effect of a repeal of the ACA. This means that the federal government has likely paid billions more each year than the law allows for the expansion population while states have spent billions less. Additionally, Gruber’s results suggest that if the ACA were repealed, a lot fewer people would likely lose coverage than previously thought.
