A war or words has escalated between the incoming Trump Administration and Boston Mayor Michelle Wu, who said the city will not cooperate with federal immigration officials should a campaign promise of mass deportations of immigrants be carried out.

Wu has said the measure is urgently needed, but a lawmaker who does not represent any part of Boston was able to stop the bill from advancing, at least temporarily.

A Republican from Norwell shut down a House session Friday for the second day in a row over concerns he has with a tax shift plan from Boston Mayor Michelle Wu that has faced renewed pushback in the Legislature this week.
