OKLAHOMA CITY (AP) — Emails exchanged by Oklahoma officials offer insight into the decision-making process that led the state to reverse course and return money to the federal government that would have gone toward implementing the federal health care law. The emails from 2011 were obtained by the Oklahoman through a public records request. Insurance Commissioner John Doak's Democratic predecessor agreed to accept a $1 million grant as part of President Barack Obama's health overhaul package. But Doak decided to return the money and Governor Mary Fallin, also a Republican, decided to return $54 million in federal funding to develop a health insurance exchange. The exchanges are a key part of President Barack Obama's Affordable Care Act. Emails show Doak's staff urged him to push for a state-based exchange while still opposing Obama's plan.
