The federal government shelled out $2.4 billion in loans to a series of non-profit health plans under Obamacare, but now they’re struggling to stay alive.

The plans, dubbed CO-OPs (Consumer Operated and Oriented Plans) were intended to increase competition in the insurance market and serve as a check on private insurers by providing an alternative that wasn’t focused on profit. They were a compromise measure intended to satisfy liberals who wanted the law to set up a fully government-run health insurance option.
