The White House has said more than 6 million people have signed up for Obamacare. But reporters have had little luck getting the administration to provide specific figures when it comes to what percentage of enrollees have actually paid a premium, which Sebelius acknowledged is required before someone is officially enrolled.
"You are not fully enrolled -- you're absolutely right -- until you pay your premium," she said. "But we also know that millions of people now have health care."
If between 80 and 90 percent of the six million have paid premiums, the number who are fully enrolled would be closer to five million than to six million.
Previously, White House press secretary Jay Carney said that general estimates suggest about 80 percent of enrollees had paid a premium.
