The administration remains tight-lipped about the problems facing healthcare.gov. After initially blaming the site's inaccessibility on heavy traffic, officials have acknowledged deeper structural problems but have not said what those problems are.
The HHS also has not said how many people have enrolled in coverage through the federally run exchanges. The White House says it plans to release monthly enrollment updates, putting the earliest possible release at Nov. 1.
"Either the administration was not ready for launch, or it was not up to the job," Upton said in a statement. "The president and top officials were quick to boast the number of visitors to HealthCare.gov, but they have since gone silent, refusing to disclose even basic enrollment figures."
