The White House is pressuring insurance companies not to speak publicly about Obama administration policies that could eliminate the existing health insurance plans of millions of Americans.

The administration made “clarifications” to the 2010 Affordable Care Act after it was passed that have already wiped out hundreds of thousands of existing health plans.

“Basically, if you speak out, if you’re quoted, you’re going to get a call from the White House, pressure to be quiet,” said CNN investigative reporter Drew Griffin on Anderson Cooper 360 Wednesday night. Insurance companies executives, Griffin said, ask heads of consulting firms not to criticize the Obamacare rollout debacle publicly.

“They feel defenseless before the White House P.R. team,” Griffin said. “The sources said they fear White House retribution.”

Prior to the Obamacare rollout, insurance companies issued warnings to the White House about the possibility of mass cancellations, which the administration ignored.
