The Trump administration on Friday formally proposed a sweeping expansion of its collection of DNA and other biometric data of immigrants, to go beyond detained migrants in order to include US citizen sponsors and others, Reuters reported.

Its proposal also vastly expands the biological information that the Department of Homeland Security (DHS) collects beyond genetic material to include eye scans, voice prints, and palm prints, the department's US Citizenship and Immigration Services said in a notice published in the Federal Register.

Friday's proposal, first announced September 1, would vastly expand such collections that DHS said would help prove family relationships, verify identities, and check criminal histories. It also moves to include children, among other changes.
