Massachusetts Gov. Maura Healey is hardening her approach to the state’s migrant crisis in the face of mounting safety concerns and just days before President-elect Trump is sworn into office.

The governor of Massachusetts has proposed that at least one member of a family staying in emergency shelters be in the country legally, hardening her stance at a time when concerns were raised about the safety at the facilties.

Families staying in Massachusetts emergency shelters must be in the U.S. legally and must also undergo a criminal background check before staying at shelters, the governor said Wednesday.
