What happens to sanctuary cities under Trump presidency?

President-elect Donald Trump has pledged to cut federal funding to sanctuary cities within his first 100 days in office, meaning San Francisco, Oakland, and San Jose could be affected if he follows through on the promise.

The mayors of each of the Bay Area’s three biggest cities said they will wait and see what happens, but they are committed to their statuses as sanctuary cities.

San Francisco Mayor Ed Lee said the city is and always will be a welcoming and diverse city.

“Our DNA is being a sanctuary city,” Lee said. “I’ve always known this city to have welcomed, protected, and made sure the immigrant families succeed along with everyone else.”

A sanctuary city means its authorities do not help federal immigration enforcement officials detain undocumented immigrants, if those immigrants are picked up for a low-level crime.

San Jose Mayor Sam Liccardo said he will stick to what works.

“Police chiefs throughout the country, most major cities that say it undermines safety in communities that have local law enforcement out there in the community enforcing federal immigration laws,” Liccardo said.

Trump wants stricter immigration laws and used the death of Kate Steinle in San Francisco as an example during his campaign. Steinle was shot by an undocumented immigrant on Pier 14 in July 2015. Her death is part of the reason Trump wants to cut federal funding to sanctuary cities across the U.S. that he believes harbor criminals.

“For the most part, cities like San Jose are not terribly dependent on federal money,” Liccardo added.

Liccardo said San Jose receives a few million dollars each year in federal funds. Lee said San Francisco receives about half a billion dollars.

“Any change in administration, we have to be very focused on what we’re doing, but also we’ve enjoyed funding from different administrations that didn’t agree with us on things like sanctuary city,” Lee said. “We have to see what happens, but we’re not going to change our DNA because of politics.”

Lee said it is possible cities could receive federal dollars for other things like helping veterans, healthcare, and transportation.
