California Attorney General Rob Bonta led 20 states in a lawsuit on Tuesday alleging the Trump administration unlawfully shared public health insurance information with Immigration and Customs Enforcement officials.

Colorado and 19 other states are suing the federal government in order to prevent Medicaid data from being shared with US Immigration and Customs Enforcement (ICE).

The data sharing violates the Medicaid Act, the attorneys general said, which allows sharing of personal information only in narrow circumstances that benefit public health and the integrity of the Medicaid program.
