Kansas and a coalition of several Republican-led states joined a lawsuit to block the Biden administration from using taxpayer-funded federal agencies to register new voters and decried it an “unlawful” overreach that could result in millions of new Democratic registrants.

The lawsuit, filed in the U.S. District Court for the District of Kansas, claims the Biden administration’s 2021 Executive Order 14019, which mandates federal agencies to engage in voter registration activities, oversteps the authority granted to the executive branch and infringes on state sovereignty.
