Los Angeles, the second largest US city, is setting itself up for a standoff with President-elect Donald Trump over immigration.
On Tuesday, its city council is poised to pass a "sanctuary city" ordinance to bar using local resources to help federal immigration authorities.
LA's public school system is also set to declare itself a "sanctuary" for undocumented immigrants and LGBTQ students in a series of emergency resolutions.
Trump, who will be sworn in in two months, has promised mass deportations once he returns to the White House. His chosen "border czar", Tim Homan, has urged sanctuary cities to "get the hell out of the way" of federal immigration crackdowns.
