SYRACUSE, N.Y. -- Mayor Stephanie Miner said Syracuse will stand defiantly against an impending federal crackdown on undocumented immigrants.

Syracuse is now and will remain a sanctuary city for immigrants, Miner declared during her State of the City address Thursday.

"I promise you that as long as I am mayor, the resources of this city, including the Syracuse Police Department, will not be used to help enforce federal anti-immigrant policies," Miner said, earning a standing ovation. "As long as I am mayor, Syracuse will be a sanctuary city for vulnerable families who had the misfortune of being born in a war-torn corner of our world."

Miner's comments come as President-Elect Donald Trump prepares to take office. Trump has repeatedly pledged to crack down on undocumented immigrants and sanctuary cities.

A sanctuary city is not an official government designation. The term refers to a city that does not detain or prosecute people for violating federal immigration laws. Such cities became a focus in last year's presidential campaign as Trump outlined strict immigration policies.

Nationwide, more than 300 cities are considered sanctuaries.

With tonight's declaration, Miner joins mayors from cities like Los Angeles, New York, Chicago and dozens more who have pledged to defy Trump's federal immigration policies. In Chicago, for example, Mayor Rahm Emanuel recently set aside $1 million for legal defense for undocumented immigrants.

New York Mayor Bill de Blasio issued a statement following the speech in which he supported Miner's stance.

"Mayors of cities large and small across New York and across the country are taking the same stance - one that New York City steadfastly supports," he wrote. "In times as uncertain as these, it is crucial that mayors band together as the first line of defense for our residents. Together, we can protect our people."

Resistance like Miner's could result in a showdown between Trump's new administration and local governments. Last year, Trump threatened to withhold federal grants for sanctuary cities. He could also sue cities that refuse to abide by federal immigration policies.

Miner said she is concerned about losing federal funding based on Trump's cabinet selections more than the city's immigration policies. She said his policies are "antithetical" to the city's progress with the exception, maybe, of infrastructure spending.

For those reasons and more, she said, she did not support Trump's bid for the presidency.

"In the 24 or 48 hours after the presidential election I had a number of people who are immigrants or new Americans reach out to me in fear," she said. "I've been part of elections that I've won and part of elections that I've lost, but this is the first time I've been part of an election where there was a fear from Americans about what their future was going to be."
