On March 6th, 2018 the Department of Justice under Jeff Sessions filed a lawsuit in a federal district court in Sacramento claiming that California has preempted federal immigration law and “impermissibly discriminate[d] against the United States” by passing The California Values Act which prevents local law enforcement from informing ICE agents when jailed immigrants are due to be released and from releasing them directly into federal custody, prohibits employers from cooperating with ICE raids, and gives the State of California the right to inspect federal detention centers to ensure that they meet appropriate health and safety standards, among other protections. Taking an unlikely position for a conservative Republican, Jeff Sessions stated that "Federal law is the supreme law of the land”. Ironically, when, in 2010, Arizona adopted SB 1070 which required non-native Americans who are "undocumented" to carry papers enabling police to arrest them without a warrant, Republicans rallied support for the State's right to formulate its own immigration policy. In Arizona v United States, in 2012, the Supreme Court ruled that Arizona overstepped its bounds in imposing those requirements. Justice Anthony Kennedy wrote in the majority opinion that, “...the state may not pursue policies that undermine federal law”. A major difference between the two State measures is that nothing in the California law prevents federal immigration agents from doing their job. In fact, in recent months, California has been openly targeted by the Trump Administration for increased ICE raids, and, in the past few weeks, hundreds of additional businesses have been raided and Californians have been detained and deported. In a press conference on March 7th, 2018, Governor Jerry Brown responded to the federal lawsuit stating, "This is basically going to war against the state of California, the engine of the American economy". "It's not wise, it's not right and it will not stand." Governor Brown called the lawsuit a "political stunt", likened it to Fox News, and added that Jeff Sessions should apologize to Californians for "bringing the mendacity of Washington to California, and trying to insert discord and dysfunction ... to a state that's actually working." https://www.cnn.com/2018/03/07/politics/jerry-brown-fires-back-jeff-sessions-donald-trump-mueller/index.html State Senate President Pro Tem Kevin de León (D-Los Angeles), author of The California Values Act, accused Sessions of having ideology based on "white supremacy and white nationalism." Senate President de Leon has enlisted the help of former U.S. Attorney General Eric Holder in formulating a legal response to the Trump Administration's lawsuit. Holder maintains that the federal government cannot legally require that a state use its resources to enforce federal immigration law. He called the Trump administration's lawsuit a "political and unconstitutional attack on the state of California's well-established rights under our system of government." Oakland Mayor Libby Schaaf made the bold decision to warn immigrant communities in advance of the federal raids in the Bay Area, citing information from "reliable sources". https://www.politico.com/story/2018/02/28/california-trump-border-wall-430742 On Tuesday, March 13th President Trump will make his first visit to California since taking office, with a plan to inspect prototypes for his proposed border wall, according to administration officials, as part of what Politico has referred to as "Trump's Border Wall Hallucination Tour". According to The New York Times, President Trump will also be attending a Republican fundraiser in Beverly Hills, with tickets costing $35,000 to $250,000.
