Suing the federal government has become the most prominent form of coordinated national AG activism in recent years.

Coalitions of AGs have sued the Trump Administration repeatedly across a range of issues, such as on immigration, health care, and environmental policy. These coalitions have been led mainly by Democratic AGs, such as Washington State’s Bob Ferguson, pictured above. During the Obama Administration, however, it was mostly Republican coalitions bringing these coordinated efforts, mostly famously challenging the constitutionality of the Affordable Care Act.

The prominence of coordinated multistate lawsuits to challenge federal policy is a relatively recent phenomenon. While states have a long history of suing the federal government, these were typically single-state efforts claiming specific harm to that state. Now, partisan coalitions of AGs have used multistate lawsuits as a way to both block federal policies and to prompt national action.
