Immigration arrests at federal courthouses have taken up most of the national attention since Donald Trump became president, but across California, U.S. Customs and Immigration Enforcement agents are showing up at state courts and arresting undocumented immigrants, CalMatters Nigel Duara reports. ICE agents were waiting outside the courthouse and arrested him. ICE agents have arrested at least two dozen other people at state courts in Stanislaus, Glenn, Los Angeles and Fresno counties. This summer in Butte County, immigration enforcement agents conducted an operation inside the county’s Oroville courthouse. Gavin Newsom signed Saturday meant to keep immigration enforcement agents out of schools and hospitals, it’s unclear what California law enforcement can actually do to enforce the law keeping agents out of courthouses.
