President Trump threatened on Twitter to end what he called "bailouts" for health insurance companies — a term he has used to refer to the payments insurers receive for the Affordable Care Act subsidies they are required to give to low-income people.

Why it matters: The Trump administration has been making the payments on a month-to-month basis, but health insurers have been worried that Trump would cut them off after the defeat of the Senate's ACA repeal plans. Without those payments, insurers warn that ACA premiums will skyrocket even more — because they still have to provide the subsidies and have to recover their costs.
