Tuesday’s demonstration from groups like the Massachusetts Immigrant and Refugee Advocacy Coalition and the Massachusetts Communities Action Network are the latest in a string of activism surrounding the Safe Communities Act.

Senator Jamie Eldridge originally introduced the act while Barack Obama was in office but tells WGBH News he re-introduced the legislation this session as President Donald Trump ordered ICE to increase enforcement against undocumented immigrants regardless of their criminal records.

Some of the measures would bar police from asking about a person’s immigration status, require law enforcement to inform an undocumented immigrant they have a right to an attorney if arrested, and prevent local police from signing up for a federal program known as 287g that allows officers to assist ICE investigations.
