Cities across the US are making preparations to protect immigrants from Donald Trump’s planned mass deportation program during his second presidency. Los Angeles passed an ordinance in November that prohibits municipal resources from being used for federal immigration enforcement.

An executive order that Trump signed Monday, shortly after he was sworn in, directs federal officials to take actions “to ensure that so-called ‘sanctuary’ jurisdictions, which seek to interfere with the lawful exercise of Federal law enforcement operations, do not receive access to Federal funds.”

As the Trump administration promises the “largest deportation operation in history,” what does that mean for cities with “sanctuary laws.”

During President Donald Trump's first televised interview since his inauguration, he said he's considering cutting federal funding to sanctuary cities as part of his policies on immigration.

The Justice Department ordered federal prosecutors to investigate state or local officials who they believe are interfering with the Trump administration’s crackdown on immigration.

Leaders of several sanctuary cities where officials had prominently rejected Trump’s first-term immigration policies are shifting their tone.

The term "sanctuary city" is not an official designation. It refers to a city, county, or municipality that has policies or laws in place to restrict local officials from working with federal immigration authorities.
