Under California's sanctuary state laws, local law enforcement can not be called on to help federal agents.
Although state laws are the center of the federal lawsuit, San Francisco put sanctuary cities on President Donald Trump's radar when Jose Garcia Zarate, an undocumented immigrant, set off the gun that ultimately killed Kate Steinle.
Sessions told law enforcement officers at a conference in Sacramento Wednesday that the Justice Department sued California because state laws are preventing federal immigration agents from doing their jobs.
Becerra, who is up for election in November, said sanctuary policies increase public safety by promoting trust between immigrant communities and law enforcement, while allowing police resources to be used to fight other crimes.
The lawsuit challenges California laws that bar police from asking people about their citizenship status or participating in federal immigration enforcement activities.
Late Tuesday the Justice Department sued to overturn three California statutes that render it more hard for officials from Immigration and Customs Enforcement (ICE) and the Customs and Border Protection (CBP) to obtain the cooperation of local officials and private employers to make arrests.
"At a time of unprecedented political turmoil, Jeff Sessions has come to California to further divide and polarize America", Brown said on Twitter.
The California laws were passed in response to Trump's promises to sharply ramp up the deportation of people living in the USA illegally.
We know that this is not about enforcing federal law.
"We extended an invitation to speak at our event", Leveroni said in a phone interview Tuesday.
The former Republican senator from Alabama admonished the Golden State's elected officials at the meeting - held blocks away from the statehouse - for passing pro-immigrant laws just one day after suing Gov.
This isn't the first time the Trump administration has attempted to attack Sanctuary states and cities. Sessions had strong words for Oakland Mayor Libby Schaaf, who issued an unusual public warning last month that she was tipped off that an immigration operation was imminent, perhaps within 24 hours.
The lawsuit also spells out in the clearest detail yet how California's much-vaunted resistance has thrown a wrench in the wheels of the administration's deportation plans. "Her actions support those who flout our laws and boldly validate the illegality", he said.
Brown speculated that Sessions' dig on California may be an attempt to ease an openly rocky relationship with the president, saying, "Maybe he's trying to keep his job because the president is not too happy with him".
In a statement previous year the association's president, Gardena Police Chief Ed Madrano, said the compromise "addresses the significant public safety concerns we raised during this debate, and it reaffirms what we have held since the beginning, which is that California law enforcement should not be used to assist in mass deportations".
"I understand that we have a wide variety of political opinions out there on immigration, but the law is in the books and its objective is clear. But it would be no different in principle from this new law enacted by California". Jerry Brown and California Attorney General Xavier Becerra in federal court.
