Tennessee Rep. Marsha Blackburn said Sunday that she and fellow House Republicans will likely grill Health and Human Services Secretary Kathleen Sebelius about the cost of the ObamaCare website when she testifies on Capitol Hill this week about the problem-plagued, online exchange.

“I want to know how much money has been spent and how much is going to be spent,” Blackburn, a member of the Republican-led House Commerce and Energy Committee, told “Fox News Sunday.”

Sebelius is scheduled to testify Wednesday in front of the committee.

The trip to Capitol Hill to testify will be the first for Sebelius since the Oct. 1 launch of the website, which has been plagued by such problems as slow response times, volume-related crashes and posting inaccurate information.

The committee last week held a hearing on the site and invited Sebelius, but she did not attend. The hearing focused on contractors’ input in the development of the estimated $678 million healthcare.gov site.

Rep. Xavier Becerra, D-Calif., told Fox News he wants to know from Sebelius “when she really believes the website will be up and running as it should.”

Officials have said the site will be ready by the end of November.
