There won't be a magic moment, but the Obama administration's much-maligned health insurance website should be able to weather an expected year-end crush of customers, officials asserted Friday.

Probing whether the White House shares blame for health care website woes, the House's chief investigator is delving into technical issues behind the dysfunctional rollout of HealthCare.gov.

The underdog of government health care programs is emerging as the rare early success story of President Barack Obama's technologically challenged health overhaul.

The focus appears to be on people whose policies have been canceled. But the president can't just pick up the phone and order the Treasury to cut checks for people suffering from insurance premium sticker shock.

It's Economics 101, a little-noticed consequence of a controversial policy decision. And there are winners and losers.

Obama administration officials are facing mounting questions about whether they cut corners on security testing while rushing to meet a self-imposed deadline to launch online health insurance markets.

Marilyn Tavenner, head of the Centers for Medicare and Medicaid Services, said the government's health care website has improved since its widely panned launch a month ago, and is still improving.

A senior government official declined to say Tuesday if the administration will support legislation to fulfill President Barack Obama's oft-stated promise that anyone who likes their health care plan will be able to keep it under the nation's new law.
