A growing number of states are opening taxpayer-funded health insurance programs to immigrants, including those living in the U.S. without authorization, even as Republicans assail President Joe Biden over a dramatic increase in illegal crossings of the southern border.

Eleven states and Washington, D.C., together provide full health insurance coverage to more than 1 million low-income immigrants regardless of their legal status, according to state data compiled by KFF Health News. Most aren’t authorized to live in the U.S., state officials say.

Enrollment in these programs could nearly double by 2025 as at least seven states initiate or expand coverage. In January, Republican-controlled Utah will start covering children regardless of immigration status, while New York and California will widen eligibility to cover more adults.

“These are kids, and we have a heart,” said Utah state Rep. Jim Dunnigan, a Republican who initially opposed his state’s plan to cover children lacking legal status but relented after compromises including a cap on enrollment.
