The federal judge overseeing a lawsuit filed by more than a dozen states to stop President Trump’s plan to cut off billions of dollars in payments to health insurance providers has decided to not issue a preliminary injunction preventing the White House from halting the subsidies.

These monthly payments, created as part of the 2010 Affordable Care Act, are provided by the federal government to insurance providers who sell qualifying healthcare plans on the individual market (aka “Obamacare”). The subsidies are intended to help insurers keep out-of-pocket expenses — like co-pays and deductibles — low, particularly for Americans making between 100% and 250% of the federal poverty line.
