- NEW: Health insurance CEOs meet with administration officials, including Sebelius
- Republicans call for her to resign or get fired over the Obamacare website problems
- The White House mounts a campaign to boost enrollment in 10 cities
- White House: Obama expected glitches, but not problems on the scale seen
Washington (CNN) -- Call it the Obamacare website fiasco, with the focus Wednesday on Health and Human Services Secretary Kathleen Sebelius after she told CNN that President Barack Obama knew nothing of the problem before it became evident starting on October 1.
Sebelius headed to the White House for an afternoon meeting with insurance industry executives, then was scheduled to leave town to participate with other officials in what the administration calls a "grassroots effort" to boost enrollment in Obama's signature health care reform system.
Republican opponents seeking to undermine the 2010 Affordable Care Act call for Sebelius to be fired for the website problems in the program overseen by her department.
They also want to delay the deadline for people to obtain health coverage under the law or face a fine, with some congressional Democrats joining that call.
Here are the latest developments:
Fixing the problems
At the White House, spokesman Jay Carney gave reporters the most detailed account yet of steps being taken to address the website problems that have included long delays, difficulties signing in and incorrect information getting relayed to insurance companies.
"We are making fixes to the existing system," Carney said, noting that developers were increasing the bandwidth and "improving site architecture" to deal with the volume of visitors to Healthcare.gov.
