Virginia Democrats on Wednesday rolled out a package of bills designed to curb federal immigration enforcement activities in the commonwealth. The legislative push comes as immigration enforcement has become one of the earliest tests of Gov. Alfonso Lopez, D-Arlington, who said they are intended to prevent immigration enforcement from interfering with access to essential services and democratic participation. Under the proposal, employees of those facilities could not knowingly allow federal immigration enforcement into nonpublic areas for enforcement purposes. Elizabeth Guzman, D-Prince William, would prohibit state and local agencies from entering into agreements that authorize officers to perform federal immigration enforcement functions.
