As House Republicans see it, there is much to talk about. Last Thursday, Rep. Fred Upton, chairman of the House Energy and Commerce Committee, sent letters to Health and Human Services Secretary Kathleen Sebelius, as well as some major Obamacare contractors, wanting to know why HHS officials were painting a rosy picture of the exchanges just weeks before it all came crashing down.

“Staff from your agency who briefed committee staff in August 2013 explained that testing of the [exchanges] was proceeding on schedule and did not identify any problems like the ones now being experienced on HealthCare.gov,” Upton told Sebelius. In addition, Upton said a top Obamacare official told the committee on Sept. 19 that consumers would have immediate and full access to Obamacare’s programs, “and they will be able to choose a plan and get enrolled in coverage beginning Oct. 1.”

That certainly didn’t happen. Citing what he calls “a host of broken promises” from the Obama administration, Upton is preparing to call those officials back for more testimony. “We want to look at the rollout, and what they said this summer,” Upton told me, “when they absolutely verified that everything was fine and dandy.”

In addition to testimony, Upton wants internal documents relating to the exchange’s design and testing, plus documents from outside experts involved.
