A new report says the White House was warned as far back as late March that the Obamacare website rollout was facing serious risks.
The report by the consulting firm of McKinsey and Company showed several of the potential problems for the website, along with Obamacare's call centers.
The firm briefed top administration officials, including Health and Human Services Secretary Kathleen Sebelius, of the possible pitfalls.
The House Energy and Commerce Committee released the McKinsey report. Republicans on the panel say it's evidence that despite White House assurances earlier this year that everything was going fine, they should have known Obamacare was facing serious problems.
