Lawmakers spent the morning questioningHealth and Human Services Secretary Kathleen Sebelius.
They want to know when she found outHealthcare.gov had major problems and who she told about them.
The cabinet secretary in charge of thetroubled health care website apologized to Americans this morning.
Kathleen Sebelius, Health and Human ServicesSecretary says, "I am as frustrated and angry as anyone with the flawed launchof healthcare.gov."
Health and Human Services Secretary KathleenSebelius took responsibility for the problems with healthcare.gov, but blamedsome of the failures on contractors.
Sebelius says, "It is the Verizon server thatfailed not healthcare.gov"
But Republicans are not satisfied.
Rep. Fred Upton says, "Healthcare .gov wasdown last night, last weekend it crashed and even this morning we got an error message."
GOP lawmakers also grilled Sebelius about whymore than two million people are getting cancellation notices for their currenthealth insurance...even though President Obama repeatedly said if you like your insurance you can keepit.
Rep. Upton says, "So he has been on the same page from the verystart, yet the regulations changed months after the bill was enacted."
Sebelius says, "If someone is buying a brandnew policy, they will have consumer protections for the first time. Many people in the individual market areunderwriten, that will be illegal."
Rep. Marsha Blackburn (R-TN) says, "Somepeople like to drink out of a red solo cup and not crystal stem. You are taking away their choice."
Many Republicans are calling for Sebelius tostep down, but so far the Secretary hasshown no signs she's leaving.
President Obama is headed to Boston todaywhere he's expected to defend his Health Care law, pointing to the slow startthe successful Massachusetts health care overhaul had back in 2006.
