Sebelius On The Hot Seat For Obamacare Website

Health and Human Services Secretary Kathleen Sebelius is just hours from entering the lion's den.

At 9 a.m. ET, Sebelius will face off with House Republicans who've been calling for her head over the botched Obamacare rollout, CNN's Brianna Keilar reports.

According to a confidential report obtained by CNN, this hearing comes after the Obama administration was given stark warnings just one month before the healthcare.gov launch that the federal healthcare site was not ready to go live.

At the hearing, Sebelius is expected to point a finger at some of the private contractors her agency hired.

Last week those very contractors pointed the finger at HHS.
