While President Donald Trump is in the midst of ramping up the federal government’s efforts to deport millions of people currently residing in the U.S. unlawfully, Republican lawmakers in Massachusetts say it’s time to change the state’s practice of ignoring immigration detainers filed by federal officials.

A proposed bill would give a 36-hour buffer for law enforcement to hold someone beyond their entitled release date if ICE has a detainer on them.

Immigration experts estimate there are between 200,000 and 350,000 undocumented immigrants living in Massachusetts.
