The U.S. Department of Justice sued the state of California Tuesday night, challenging provisions in three immigration-related state laws as unconstitutional, according to senior Justice Department officials.

The lawsuit alleges portions of the laws are pre-empted by federal law, and therefore violate the Constitution's supremacy clause. In addition to the state, the lawsuit will be filed against California Gov. Jerry Brown and Attorney General Xavier Becerra. The DOJ will ask for a preliminary injunction against the laws.

The challenged laws include SB 54, the so-called “sanctuary state” law that limits state law enforcement interactions and information sharing with immigration authorities; AB 450, which bars private employers from cooperating with immigration agents in certain ways; and AB 103, which allows the state attorney general to inspect federal immigration detention facilities. Brown signed each of the bills last year.

U.S. Attorney General Jeff Sessions is expected to formally announce the lawsuit in a speech in Sacramento on Wednesday morning, at the California Peace Officers Association's annual Law Enforcement Legislative Day.

“The Department of Justice and the Trump administration are going to fight these unjust, unfair, and unconstitutional policies that have been imposed on you,” Sessions is expected to tell the group, according to prepared remarks. “We are fighting to make your jobs safer and to help you reduce crime in America. And I believe that we are going to win.”

Brown said on Twitter Tuesday that Sessions had “come to California to further divide and polarize America.”

“Jeff, these political stunts may be the norm in Washington, but they don't work here. SAD!!!” the governor tweeted.

Becerra also tweeted in response: “No matter what happens in Washington, #California will stay the course and enforce all our laws and protect all our people. That's how we keep our communities safe. #Immigration.”

On a call with reporters, Becerra said the state's laws work “in concert” with federal laws, and that the state “stands on strong legal footing.”

“States and local jurisdictions have the right to determine which policies are best for their communities,” Becerra said. “Many throughout the nation have found that public safety is better served by focusing their time as law enforcement officials and their resources on combating dangerous criminals rather than on immigration enforcement.”

When he signed SB 54 into law, Brown said in a signing statement that the legislation did not “prevent or prohibit Immigration and Customs Enforcement or the Department of Homeland Security from doing their own work in any way.”

The complaint will be filed in the U.S. District Court for the Eastern District of California in Sacramento. DOJ officials said the venue was chosen because the state capital is there. The decision to file the lawsuit was made after a serious review of the state's laws, the officials said, and other jurisdictions could face similar actions pending the outcome of ongoing reviews.

The lawsuit will be handled by lawyers in the DOJ's Civil Division, as well as the U.S. attorney for the Eastern District of California, McGregor Scott. The nominee to lead the Civil Division, Jody Hunt, is also expected to have his hearing before the Senate Judiciary Committee on Wednesday. The division is currently led by an acting assistant attorney general, Chad Readler.

Brown and Becerra are vocal critics of President Donald Trump's immigration agenda. The state is currently engaged in litigation against the administration's “sanctuary city” policy, which withholds grant money from states and jurisdictions that do not comply with certain information-sharing requirements. Just this week, U.S. District Judge William Orrick denied the state's request for a preliminary injunction against the policy.

The government's lawsuit claims the state laws are obstacles to the government's execution of provisions in the Immigration and Nationality Act, and are invalid because they seek to directly regulate the federal government.

Under President Barack Obama, the DOJ sued Arizona over that state's 2010 immigration law. In 2012, the Supreme Court struck down portions of the law, but left in place its most controversial provision, which allowed police to check the immigration status of people they detained. In the majority opinion, Justice Anthony Kennedy wrote that the government has “significant power to regulate immigration.”

“Arizona may have understandable frustrations with the problems caused by illegal immigration while that process continues, but the state may not pursue policies that undermine federal law,” the justices wrote.
