California is spearheading a lawsuit involving 20 state attorneys general against the Trump administration. The suit aims to prevent health officials from sharing Medicaid data with the Department of Homeland Security (DHS). The attorneys general argue that sharing this sensitive health information with DHS for immigration enforcement purposes is unlawful and a violation of patient privacy. They seek a court order to permanently block this data sharing arrangement, protecting access to healthcare and preventing the use of personal health information for immigration-related actions.
