WASHINGTON — The Trump administration violated federal privacy laws when it turned over Medicaid data on millions of enrollees to deportation officials last month, California Attorney General Rob Bonta alleged on Tuesday, saying he and 19 other states’ attorneys general have sued over the move.

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.
