(Adds CMS comment in 8th paragraph)
By David Morgan
WASHINGTON, Nov 15 (Reuters) - Almost three months before the botched launch of HealthCare.gov, a U.S. health official expressed frustration with a main contractor working on the website, fearing quality assurance issues could "crash the plane at take-off," according to government documents obtained by Reuters.
The documents were released by Republican investigators with the House of Representatives Energy and Commerce Committee. Republican lawmakers, who have consistently sought to undermine President Barack Obama's signature health system overhaul, are probing the law's disastrous rollout.
Two series of internal emails in July between officials at the Centers for Medicare and Medicaid Services (CMS), including HealthCare.gov project manager Henry Chao, describe struggles with contractors, staff shortages and software problems long before the federal healthcare website crashed on its Oct. 1 launch and threw the rollout of Obamacare into political turmoil.
In a July 16 email sent ahead of a meeting with then-prime contractor CGI Federal, Chao describes the agency's low confidence level in the project work, from constant struggles with releases to changing delivery dates and poor quality assurance on software.
"I just need to feel more confident they are not going to crash the plane at take-off," Chao says in the email, which was among several documents the Republican investigators released.
Officials at CGI Federal, the U.S. subsidiary of Canada's CGI Group Inc, were not immediately available for comment.
In congressional testimony released Oct. 23, CGI Federal blamed early website problems on another contractor's software and also said the federal government was ultimately responsible for the website's performance.
CMS said in a statement about Chao's July 16 email: "This email discusses one small piece of ongoing discussions about managing deliverables and communicating expectations that were on a short timeline to meet October 1st. Management concerns about meeting timelines are expected for any project of this size and scope."
CMS declined to make Chao, the deputy chief information officer at CMS, available to speak directly with Reuters.
President Barack Obama and administration officials have come under fire for launching a malfunctioning website, but it's not clear if officials knew the extent of the site's problems or when they knew.
A day after writing the email about CGI, Chao assured a House Oversight and Government Reform subcommittee that HealthCare.gov would be ready on time.
It is not known whether Chao learned new information to change his assessment in the intervening hours.
On July 20, he distributed a video link to the testimony via email and urged CMS staff to make good on the pledge to lawmakers.
"I wanted to share this with you so you can see and hear that both Marilyn and I under oath stated we are going to make Oct. 1," Chao wrote, referring to CMS chief Marilyn Tavenner.
"I would like you (to) put yourself in my shoes standing before Congress, which in essence is standing before the American public, and know that you speak the tongue of not necessarily just past truths but the truth that you will make happen."
But HealthCare.gov, the federal government's health insurance marketplace portal for millions of uninsured people in 36 states, crashed shortly after its launch and has been plagued by technical problems even since. (Reporting by David Morgan; Editing by Karey Van Hall and Lisa Shumaker)
