Immigration and Customs Enforcement agents are reportedly poised to arrest more than 1,500 undocumented immigrants in the region around the Bay Area in California in a maneuver apparently intended to send a signal to sanctuary cities across the country, the San Francisco Chronicle reports. Gov. Jerry Brown (D) signed statewide sanctuary legislation for California in October, leading acting ICE Director Thomas Homan to tell Fox News that the state "better hold on tight." The upcoming sweep will target "people who have been identified as targets for deportation, including those who have been served with final deportation orders and those with criminal histories," the Chronicle reports based on conversations with someone familiar with ICE's plans, although "the number could tick up if officers come across other undocumented immigrants in the course of their actions and make what are known as collateral arrests."
