THE HILL: Republicans open investigations into ObamaCare’s disaster sites.

Republicans are launching investigations into three state-run ObamaCare exchanges that are failing disastrously.

Lawmakers are setting their sites on exchanges in Oregon, Maryland and Massachusetts where Democratic governors embraced the healthcare law, and are demanding to know why their expensive online portals remain useless more than four months after launch.

On Wednesday, four Republicans on the House Energy and Commerce Committee sent a letter to the Government Accountability Office (GAO) requesting a review of the $304 million in federal grants that Oregon received to build its broken website.

“The catastrophic breakdown of Cover Oregon is unacceptable, and taxpayers deserve accountability,” wrote the group of lawmakers led by Rep. Greg Walden (R-Ore.).

The scrutiny of the state enrollment portals is a shift from October, when the federal site HealthCare.Gov was out of service but state-run exchanges in California, New York and even red Kentucky appeared to be humming along.

But several states are having major problems with their ObamaCare sites.

In Oregon, not even one person has yet to enroll online, leaving the state completely reliant on paper applications.

Wow. Not one person after all these months.
