It's one data point Obama administration officials have yet to disclose: just how many new health care enrollees have actually paid their premiums.
As the Obama administration released its latest enrollment figures Wednesday, officials broke down some of the demographics on consumers who are signing up for coverage. But White House officials have so far not provided data on how many people have sent in their payments to activate their plans.
Asked for that information Wednesday, White House Press Secretary Jay Carney pointed to the insurance companies as the best source for that metric.
"It is a contract between an individual or -- well, an individual even representing his or her family -- and a private insurance provider. So insurance companies obviously have data about when those payments are made," Carney told reporters at Wednesday's press briefing.
