Stewart vs. Azar:  A group of low income residents of Kentucky challenged the Trump administration’s move to allow Kentucky to impose work requirements on enrollees in the state Medicaid requirement

New York vs. Acosta  A group of 12 Democratic attrorneys general are challenging a Trump administration regulation that allows for easier creation and coordination of Association Health Plans.  This allegedly violates the ACA aim of establishing minimum insurance standards
