As state attorneys general on Tuesday won their motion to intervene in a lawsuit challenging the legality of insurer subsidies under the Affordable Care Act, a U.S. business group also urged the U.S. Department of Health and Human Services to keep the subsidies in a letter sent last month.

In a letter to the Health and Human Services Department dated July 12, the U.S. Chamber of Commerce — in response to request for comments on reducing regulatory burdens in the Federal Register — stated that while the chamber shares the department’s goals, including stabilizing the individual and small group health insurance markets, “HHS should make a firm commitment to pay the CSRs [cost-sharing reductions] until additional legislative relief can provide necessary certainty.” The Trump administration has threatened to cut off the subsidies if Congress does not enact repeal of the ACA.
