Sen. Ben Sasse (R-Neb.) is throwing up roadblocks to the confirmation of two top Department of Health and Human Services (HHS) nominees over what he describes as “systematic failures” of an ObamaCare program for start-up insurers.

“I will act to block consideration and confirmation of every [HHS] nominee until families who lost their co-op insurance plans get straight answers,” Sasse announced in a press release Monday.
