Meanwhile, the Orange County Sheriff's office announced this week it will make publicly available the inmate names and release dates through an online database, regardless of the released person's immigration status. The sheriff also directed staff to respond to requests from ICE for any serious offender criminals who are on the inmate release list.
"SB 54 makes local law enforcement's job more difficult and requires bureaucratic processes that could allow dangerous individuals to fall through the cracks of our justice system," Sheriff Sandra Hutchens said in a statement. "My department, however, remains committed to cooperating fully with federal authorities in all areas where I have discretion to remove serious criminals from our community."
California's attorney general, Xavier Becerra, pushed back against criticism of the law.
"We're not going to let the Trump administration coerce us into doing the federal government's job of enforcing federal immigration law. We're in the business of public safety, not deportation," Becerra said in a statement Wednesday.
The state attorney general also released new "guidance" for California's public safety authorities under SB 54. Among other things, it lays out how local police agencies can provide inmate release information to immigration authorities and what is needed to stay in compliance with the state law.
Kevin de Leon, who introduced SB 54 legislation last year and was until last week the Democratic leader of the state Senate, lashed out at Orange County's vote Tuesday to side with Trump's lawsuit against California.
"The county that gave us Prop 187 more than two decades ago is at it again with another unconstitutional attack on our immigrant communities," said de Leon, who is challenging incumbent U.S. Sen. Dianne Feinstein, also a Democrat, in a primary. "I am confident the courts will reject this challenge to SB 54, just as they roundly rejected Prop 187."
Proposition 187, a 1994 ballot initiative championed by prominent state Republicans and passed by voters, was a ban on most social services to undocumented immigrants. Eventually, courts ruled that it was unconstitutional, but it still is considered a polarizing issue that some blame for hurting the state's GOP support among Latinos.
The Orange County moves are part of a backlash against sanctuary laws in traditionally Republican areas of the country.
On Monday, the Texas attorney general weighed in as part of a coalition of 18 Republican-led states filing a so-called friend-of-the-court brief supporting the Trump administration's case against California's sanctuary law.
"Dangerous sanctuary policies like California undermine the rule of law and endanger good law enforcement officers and the communities that need their protection the most," said Ken Paxton, the Republican attorney general of Texas.
