Attorney General Jeff Sessions announced the lawsuit Wednesday at an annual gathering of law enforcement organizations in Sacramento.
Both are scheduled to speak at a California Peace Officers Association event Wednesday, at Sacramento's Sawyer Hotel. "We are fighting to make your jobs safer and to help you reduce crime in America. I appreciate the efforts of Attorney General Jeff Sessions and the Department of Justice to uphold the rule of law and protect American communities". The Supreme Court sided with the Obama administration by striking down major provisions of that law in 2012.
"I think the record will speak for itself that we've proven that not only is California doing things the way it should, but we've also proven that on numerous occasions, the Trump administration has acted outside the law", Becerra said.
Administration officials charge that the state measures not only hinder their ability to carry out federal law, but also put immigration agents and communities at risk.
The suit, filed in the federal court in the eastern district of California, challenges three statutes that the state has passed in support of cities that have refused to meet the demands of federal immigration authorities to hand over undocumented immigrants for prosecution or expulsion.
Brown responded in a statement by calling the lawsuit a "political stunt".
"At a time of unprecedented political turmoil, Jeff Sessions has come to California to further divide and polarize America", Brown said on Twitter.
Then, in a direct shout-out to the attorney general, Brown wrote, "Jeff, these political stunts may be the norm in Washington, but they don't work here".More news: Strong aftershock hits Papua New Guinea
Leveroni's law enforcement advocacy organization has publicly opposed Senate Bill 54, which Governor Jerry Brown signed into law previous year making California a Sanctuary State.
The lawsuit was filed late Tuesday in Sacramento. In this case, it is California that is arguably in uncharted legal territory, imposing barriers aimed at undermining federal law enforcement efforts. "But they can't get in the way of state public safety enforcement". "We're in the business of public safety, not deportation".
California is home to some high-profile sanctuary cities, including San Francisco and Oakland.
It seems the Trump administration is now following through on the president's tough rhetoric.
The centerpiece of California's resistance to President Donald Trump's promised immigration crackdown, the law limits who state and local law enforcement agencies can hold, question and transfer at the request of federal immigration officials, and it bars officers from inquiring about a person's immigration status.
In the case of HB 450, the California State Assembly's Judiciary Committee made clear they were passing this law specifically because of "an expected increase in federal immigration enforcement". The state wants a judge to certify that its laws are in compliance with federal immigration law.
The pending DOJ lawsuit is a separate legal matter from challenges against the Trump administration's threats to withhold federal grants from jurisdictions over "sanctuary" policies, which are playing out in courts in California and IL.
