Speaking to reporters at a press conference, Bingman said the House-passed measure won't be heard, warning that the lure of $54 million in federal grant money could lead the state into a "trap" of complying with the new federal health care law.

"We're concerned about actually falling into the trap … of adopting the Obamacare, which is really what we're against," said Bingman, R-Sapulpa. "If we can put together a private exchange that's separate from that without using the federal dollars — using state dollars, using private funds — find out what the cost would be to implement something like that."

Bingman's sudden announcement appeared to expose a rift among Republicans, who control both chambers of the Legislature and the governor's office for the first time in state history. Many Republicans campaigned last year on their opposition to the federal health care plan, and a state ballot question in November designed to allow the state to opt out of the federal health care plan passed with nearly 65 percent of the vote.
