An HHS official confirmed Saturday that the secretary would not attend, citing a conflict in her schedule.

“We are in close communication with the committee and have expressed our desire to be responsive to their request,” the official said.

The hearing, before the House Energy and Commerce Committee, was scheduled this week to address glitches in the Obamacare website. Chairman Fred Upton, R-Mich., ripped Sebelius when initial reports indicated she would not attend.

“Secretary Sebelius had time for Jon Stewart, and we expect her to have time for Congress,” he said in a statement, referring to her appearance last week on Comedy Central’s “The Daily Show.”
