The American Civil Liberties Union is announcing an effort in Maryland to limit local police involvement in immigration enforcement.
ACLU officials said Tuesday in Hyattsville that Democratic state Sen. Victor Ramirez of Prince George's County will sponsor the legislation, dubbed the Maryland Trust Act.
Ramirez didn't immediately respond to queries from The Associated Press. His chief of staff said Monday that details of the bill weren't complete.
Maryland immigration reform advocates have been pushing for a bill similar to the California Trust Act, signed into law last month. It prohibits police from holding immigrants for transfer to federal immigration authorities unless they've been charged or convicted of certain serious crimes.
The ACLU says in a report that local police agencies waste resources by honoring federal immigration detainers.
