Centers for Medicare and Medicaid Services administrator Marilyn Tavenner maintained that people who like their health care plan can keep it under Obamacare, despite admissions to the contrary by President Obama's spokesman and revelations by NBC News that federal officials have known for three years that millions of Americans will lose their coverage.

"It is a true statement," Tavenner replied when Rep. David Reichert, R-Wash., asked her about Obama's famous "if you like your health care plan, you can keep your health care plan" pledge.

Tavenner was testifying before the House Ways and Means Committee hearing on the technical difficulties marring the rollout on Oct. 1.

Tavenner's defense of Obama on Tuesday contradicts White House press secretary Jay Carney's reply to reporters during the Monday briefing.

"So it’s true that there are existing health care plans on the individual market that don't meet those minimum standards and therefore do not qualify for the Affordable Care Act," Carney said.
