Health and Human Services Secretary Kathleen Sebelius says the government is making “tremendous progress” toward fixing what she called a broken health system.

Sebelius commented Friday after President Barack Obama announced her resignation after five years in his Cabinet.

The former Kansas governor was blamed for the disastrous start to sign-ups for coverage under Obama’s health care law. But the administration rebounded and exceeded expectations by getting more than 7 million people to sign up for health insurance.

Sebelius says her work at HHS is the most meaningful she’s ever been a part of. She called it “the cause of my life.”

There was one more glitch on her way out the door. Sebelius lost her way while reading her statement, then said: “Unfortunately, a page is missing.”
