And they are raising concerns about the privacy of information that applicants submit under the new system.

GOP officials said Sunday that the Obama administration will face intense scrutiny this week to be more forthcoming about how many people have actually succeeded in enrolling for coverage in the new insurance markets.

The head of Medicare is scheduled to appear during a House hearing on Tuesday, followed Wednesday by Sebelius before the House Energy and Commerce Committee. The officials will also be grilled on how such crippling technical problems could have gone undetected prior to the website's Oct. 1 launch.
