Boston has become the latest city to take steps to protect its immigrant population from President-elect Donald Trump's mass deportations: its city council voted unanimously to maintain its status as a sanctuary city, The Latin Times reports.

"It's not just a policy, but it's a promise to our immigrant neighbors that they are welcome here, and this is a safe haven, and they don't have to live in fear of being unfairly scrutinized or even ripped away from their families," Councilwoman Gabriela Coletta Zapata said at Wednesday's city council meeting.

Trump has threatened to withhold federal funding from sanctuary cities, but Mayor Michelle Wu recently said she will protect undocumented immigrants in “any way possible.” Other cities taking steps in this direction include Denver, Philadelphia, Chicago and Los Angeles. In the latter, the new LAPD chief has said he will work to protect immigrants, as reported by Latino Observatory.

Historically welcoming New York City is now in contrast to Mayor Eric Adams, who is taking a harder line. He incorrectly said earlier this week that undocumented immigrants are not entitled to due process under the U.S. Constitution. “The Constitution is for Americans,” Adams told reporters at his weekly City Hall press conference. “I’m not someone who snuck into this country. My ancestors have been here a long time.” Adams also argued that undocumented people who have committed crimes should be deported, suggesting that immigration authorities should not wait for them to be tried.

Adams also repeated his desire to ease the city’s sanctuary rules, which restrict city officials from cooperating with federal immigration agents. New York City mayors since Ed Koch, who was in office from 1978 to 1989, have pointed to sanctuary policies to encourage immigrants to use city services such as hospitals, schools and police without fear of deportation, according to Gothamist.
