With just three days until Donald Trump is inaugurated as the next president of the United States, a showdown is looming between the incoming administration and leaders of approximately 300 so-called "sanctuary cities."
In sanctuary cities, local officials limit their cooperation with federal immigration officials seeking help in identifying, and potentially detaining, immigrants who are in the country illegally.
On the campaign trail, Trump promised again and again to block funding for sanctuary cities. In August in Phoenix, Arizona, he said: "We will end the sanctuary cities that have resulted in so many needless deaths. Cities that refuse to cooperate with federal authorities will not receive taxpayer dollars. And we will work with Congress to pass legislation to protect those jurisdictions that do assist federal authorities."
Somerville Mayor Joseph Curtatone has been vocal about his support for sanctuary cities, promising constituents that "Somerville will remain a sanctuary city no matter what happens in Washington."
