Questions continue to swirl around HealthCare.gov rollout

(CBS News) More than two weeks have passed since HealthCare.gov went live. Uninsured Americans are trying to sign up for coverage, but complaints are growing louder every day, especially from Congress.

It's still unknown how many Americans have been able to enroll and finding people who have enrolled difficult, CBS News correspondent Jan Crawford reported. And now, CBS News has learned members of the House Energy and Commerce Committee are launching an investigation into what has gone wrong.

Special Section: Obamacare Kicks Off

The president now acknowledges the problems with HealthCare.gov are more serious than he initially led on. "The web site that was supposed to do this all in a seamless way has had way more glitches than I think are acceptable," Mr. Obama said Tuesday in an interview with KCCI-TV.

It was a different President Obama two weeks ago when he tried to compare the health care rollout to the launch of a new iPhone. He said on Oct. 1, 2013, "Within days, they found a glitch, so they fixed it. I don't remember anybody suggesting Apple should stop selling iPhones or iPads."

Except the problem with the web site is it hasn't been fixed. Even supporters, such as the president's former press secretary, Robert Gibbs, say someone should be fired. Gibbs didn't name names, but the head of the Republican Party is pointing straight to the top, calling on Health and Human Services Secretary Kathleen Sebelius to go.

Sebelius isn't talking -- at least not since her interview on "The Daily Show" last week went viral after she fumbled her way through it.

Asked host Jon Stewart how many have signed up thus far, Sebelius said, "Fully enrolled? I can't tell you because I don't know."

At this point, the failures are well-documented, but the success stories are not. The administration is refusing to release numbers on how many people have been able to enroll, although press secretary Jay Carney, for the first time Tuesday, managed to identify a few: a woman in Illinois, a couple in Mississippi, and a family in Utah.

Remember, 7 million people is the sign-up target by the end of March. For Republicans, it's like shooting fish in a barrel, Crawford reported. Rep. Chris Stewart, R-Utah, said, "$634 million, that's how much it cost to develop Obamacare Web site. Facebook operated for six years on less money than that."

Crawford added on "CBS This Morning" that the president can be grateful for one thing: "Think about the backlash, the criticism, the complete failure of this rollout would be getting if Republicans had focused on this instead of waging that shutdown fight."
