In much-awaited testimony today on the botched ObamaCare rollout, Health and Human Services Secretary Kathleen Sebelius is facing lawmakers to answer for the botched rollout of ObamaCare.

If you can't watch the hearing on Fox News Channel, keep checking back here for video highlights.

In her opening remarks, Sebelius apologized to the American public.

“In these early weeks, access to has been a miserably frustrating experience for way too many Americans, including many who have waited years, in some cases their entire lives, for the security of health insurance. I am as frustrated and angry as anyone with the flawed launch of So let me say directly to these Americans, you deserve better. I apologize.”

Committee chairman Fred Upton (R-MI) immediately went after Sebelius on Americans who say they are losing their health insurance plans. He pressed her on when changes were made to the ObamaCare regulations that ended up forcing people off health care plans that they liked.

Sebelius said no change was ever made and that plans in place when the bill was signed were "grandfathered in."

Rep. Marsha Blackburn (R-TN) questioned Sebelius about whether President Obama broke his promise that Americans could keep their existing health care plans.

Blackburn cited numerous reports that plans were being canceled, which Sebelius defended as common, saying, “Insurance companies cancel individual policies year in and year out. They are a one-year contract with individuals.”

Blackburn blasted back, “Some people like to drive a Ford, not a Ferrari and some people like to drink out of a red solo cup, not a crystal stem. You’re taking away their choice.”

Rep. Joe Barton (R-TX) questioned Kathleen Sebelius at this morning's House hearing on the ObamaCare rollout problems.

He quoted the "Wizard of Oz," telling the former Kansas governor that "we're not in Kansas anymore."

He then pressed her on privacy concerns with

New Jersey Congressman Frank Pallone (D) praised Sebelius and chided his Republican colleagues for trying to sabotage the law.

He described the reports of Americans’ health insurance plans being canceled as “just another red herring" in the GOP's effort to scare people about ObamaCare.

Rep. John Shimkus (R-IL) questioned Sebelius on why President Obama continued to say that Americans would be able to keep their existing insurance plans.

He then pressed her on providing lawmakers with a list of providers in the federal insurance exchanges that do not offer abortion coverage in their policies. Shimkus argued that the plans that offer abortion coverage should be clearly identifiable.

New York Congressman Eliot Engel (D) blasted Republicans for repeatedly pushing for ObamaCare to be repealed, saying they are rooting for failure and "are on the wrong side of history."

Rep. Mike Rogers (R-MI) grilled Sebelius about the level of security of the ObamaCare website, arguing that the site launched with a "completely unacceptable level of security."

Rogers accused HHS of failing to make sure that "basic testing" was done to ensure that users' personal information could not be compromised.

Rep. Steve Scalise (R-LA) asked whether the contractors hired to create delivered on what they were paid huge sums to build.

Rep Gregg Harper (R-MS) tried to get Sebelius to admit that the president is responsible for the rollout.

"I appreciate you accepting responsibility for these initial rollout failures that we've had, but who is ultimately responsible? It is the president, correct?" he asked.

Sebelius disagreed, saying "we are responsible for the rollout," but then agreed with Harper that she "answers to" President Obama.

Colorado Congressman Cory Gardner (R) asked Secretary Sebelius why she wasn’t participating in the program.

“Why aren’t you in the exchange? You’re in charge of this law, correct? Why aren’t you in the exchange?” Gardner asked.

Sebelius responded that given that she has affordable, available health insurance through her employee, she is not eligible to participate in the exchange, and it would in fact be illegal.

After a contentious exchange with Rep. Billy Long (R-MO) on why she was not going to enroll in an ObamaCare health plan, Sebelius was caught off-mic, saying "don't do this to me."
