A new report dives into the problem-plagued development of the ObamaCare website and finds repeated warning signs that went unheeded before its failed launch.

President Obama has called the launch of healthcare.gov a “well-documented disaster,” and a Department of Health and Human Services Inspector General report provides a new in-depth look at the problems and lessons learned.

The IG report finds that the Centers for Medicare and Medicaid Services, which oversees healthcare.gov, received 18 “documented warnings” of problems with the site’s construction between July 2011 and July 2013. But the warnings were either not communicated across the agency or not acted upon, the report says.

A response to questions from Senator John Cornyn (R-TX) about federal spending on state-based ObamaCare exchanges reveals the improper spending of one million dollars in Arkansas. The states setting up their own exchanges have spent more than $3.2 billion in federal funds, and many of those states have presided over failed exchanges and have opted to have their citizens routed to the federal healthcare.gov ObamaCare exchange.

Responding to Sen. Cornyn, Centers of Medicare and Medicaid Services Acting Administration Andrew Slavitt wrote, “as part of CMS’s routine federal oversight of (exchanges), CMS found that the Arkansas SBM spent approximately $1 million of the state’s federal grant funding for activities that are not allowed under regulations.”

In a recent letter addressed to Senator John Cornyn (R-Texas), ObamaCare chief Andy Slavitt said the federal government will “recover its fair portion” of funds in the event a failed ObamaCare state exchange reaches a settlement with contractors.

Given that the federal government funded the overwhelming majority of state exchange projects with $5.5 billion in taxpayer funds, “fair portion” should be close to 100 percent.

Recently, Maryland reached a $45 million settlement with a contractor stemming from its state exchange debacle. But despite financing the Maryland exchange to the tune of nearly $200 million the federal government will receive only 70 percent of funds from the settlement.
