The California Peace Officers Association said the conflicting rules are creating confusion for police on the street and are now looking for Sessions to clarify those issues.
Under Trump, the department has brought a mix of political and financial pressures to bear against sanctuary cities, threatening to cut off federal law enforcement grants unless cities agree to identify and hold suspected immigration offenders.
Re Justice Department sues California over "sanctuary" laws that aid those in US illegally (March 7): This is the tyranny that the Founding Fathers feared.
"California is using every power it has - and some it doesn't - to frustrate federal law enforcement. Brown also talked about the contributions undocumented immigrants have made to his state, saying millions have lived and worked here for many years and are a big part of California's economy, which the governor called the "engine" of America's economy". Justice Department officials said that violates the Constitution's supremacy clause, which renders invalid state laws that conflict with federal ones.
Sessions says California's laws are unconstitutional and a "plain violation of common sense". In its lawsuit, the federal government argued that it forces the release of immigrants who have already shown a willingness to engage in criminal activity. "Our track record so far when it comes to any dispute with the federal government has been pretty good", Becerra said. California officials remained defiant, with Democratic Gov.
In an additional swipe, the governor declared: "We know the Trump administration is full of liars". He had particularly strong words for Oakland Mayor Libby Schaaf, who issued an unusual public warning last month about an immigration operation. "We're in the business of public safety", Becerra tweeted, "not deportation".
Brown told reporters shortly after Session's speech to law enforcement officials Wednesday that it was unprecedented for him to "act more like Fox News than a law enforcement officer". One of the other laws challenged in the lawsuit, which restricts state employers from allowing immigration agents into their workplaces, was more of an open legal question, he said.
In the time since Donald Trump won the presidential election, there has been an increasing amount of tension between lawmakers in Washington DC and lawmakers in California.
Brown and California Attorney General Xavier Becerra are directly named in the suit - and are ready for the fight.
"Those are 800 wanted criminals that are now at large in that community - 800 wanted criminals that ICE will now have to pursue by other means, with more difficulty in risky situations - all because of one irresponsible action", Sessions said. "But it would be no different in principle from this new law enacted by California".
He added that "ICE agents do incredible work every day, they're not backing down, they're not going to be deterred, and we're not going to stop enforcing the law in Alabama, or California, either, for that matter".
