Becerra announced the legal challenge standing in front of the existing border fencing at Border Field State Park near San Diego, saying the federal government failed to comply with federal environmental laws and relied on federal statutes that don’t authorize border wall projects in San Diego and Imperial counties. 
  
 “No one gets to ignore the laws. Not even the president of the United States,” Becerra said. “The border between the U.S. and Mexico spans some 2,000 miles. The list of laws violated by the president’s administration in order to build his campaign wall is almost as long.” ||||| California Attorney General Xavier Becerra announced Wednesday that the state will sue the Trump administration over one of President Trump’s paramount campaign promises—the border wall. 
  
 Becerra’s lawsuit, which targets planned projects in San Diego and Imperial counties, marks the latest shot in California's legal and legislative war against Trump. 
  
 The state essentially has emerged as the heart of the Trump "resistance," pumping out lawsuits against his immigration policies and even passing a resolution Friday in the Assembly censuring Trump for his comments on the violence stemming from white nationalist protests in Charlottesville, Va. 
  
 Becerra's latest lawsuit charged that the Trump administration "violated the U.S. Constitution, failed to comply with federal and state environmental laws, and relied on a federal statute that does not authorize the proposed projects." 
  
 "The Trump administration has once again ignored laws it doesn't like in order to resuscitate a campaign talking point to build a wall on our southern border," Becerra said in a statement Wednesday. "President Trump has yet to pivot from candidate Trump to leader of a nation built on the rule of law. That's dangerous." 
  
 The lawsuit comes as Trump works with Congress to try and secure funding for a border wall -- though the specifics of the project itself remain unclear. 
  
 The president issued an executive order in January calling for securing the “southern border of the United States through the immediate construction of a physical wall on the southern border, monitored and supported by adequate personnel so as to prevent illegal immigration, drug and human trafficking and acts of terrorism.”

 Last month, the administration awarded contracts to four companies to begin construction. 
  
 The president tweeted last week that “the WALL, which is already under construction in the form of new renovation of old and existing fences and walls, will continue to be built.” 
  
 White House Press Secretary Sarah Sanders underscored the president’s commitment to the border wall earlier this month. 
  
 “I don’t think the president has been shy about the fact that he wants a wall,” Sanders said. “It’s certainly something he feels is an important part of a responsible immigration package.” 
  
 This isn’t Becerra's first lawsuit against the Trump administration. Just last week, Becerra joined state attorneys general from Minnesota, Maryland and Maine in filing suit against the administration over its decision to end the Deferred Action for Childhood Arrivals program, arguing that the White House violated the Constitution and federal laws by rescinding the Obama-era program. 
  
 But Trump has put the onus on Congress to draft legislation that would protect ‘Dreamers,’ even meeting with Democratic congressional leadership last week to discuss a path forward. 
  
 California has been firmly against most Trump administration immigration policies. The state’s legislature also passed a sanctuary state measure over the weekend and is awaiting approval by Democratic California Gov. Jerry Brown that would bolster protections for illegal immigrants in the state—a move Attorney General Jeff Sessions called “unconscionable” on Tuesday. 
  
 “The bill risks the safety of good law enforcement officers and the safety of the neighborhoods that need their protection the most,” Sessions said during a speech in Portland, Ore., on Tuesday. “There are lives and livelihoods at stake.” 
  
 Sessions urged Brown not to sign the law that would halt local police from cooperating with federal authorities to deport illegal immigrants. 
  
 The Trump administration has faced significant roadblocks in efforts to crack down on jurisdictions that do not cooperate with federal immigration agents. Last week, a federal judge in Chicago ruled that Sessions could not withhold public grant money from sanctuary cities for refusing to follow federal immigration law—an option the attorney general has used to threaten states and localities who call themselves ‘sanctuaries.’ 
  
 “We strive to help state and local law enforcement,” Sessions said. “But we cannot continue giving such federal grants to cities that actively undermine the safety of federal law officers and actively frustrate efforts to reduce crime.”

 SAN FRANCISCO (Reuters) - California filed a lawsuit on Wednesday over the Trump administration’s plan to construct a wall along the border with Mexico, adding to the obstacles facing one of the Republican president’s key campaign promises. 
  
 President Donald Trump has insisted Mexico would pay for building the wall, which experts said could cost about $22 billion and take more than three years to complete. 
  
 With Mexico refusing to pay, Trump has said since taking office in January that the wall will initially need U.S. funding but that he will find a way to make Mexico ultimately pay for it. 
  
 Democrats in the U.S. Congress, however, firmly oppose the border wall, and at least some Democratic senators would need to vote for its inclusion in a spending package. 
  
 Democratic attorneys general including California’s Xavier Becerra have sued the Trump administration on a range of issues. 
  
 The border wall lawsuit filed in a San Diego federal court alleges that Trump’s wall violates federal environmental standards, as well as constitutional provisions regarding the separation of powers and states’ rights. 
  
 Representatives for the U.S. Justice Department declined to immediately comment on the case. 
  
 The lawsuit asks a judge to stop the administration from building the wall until it demonstrates compliance with environmental laws, and issue an order that the Department of Homeland Security cannot waive any federal guidelines in order to facilitate the project. 
  
 Last month the Trump administration said it had selected four construction companies to build concrete prototypes for a wall, which will be will be 30 feet (9 meters) tall and about 30 feet wide and will be tested in San Diego. |||||

“No one gets to ignore the laws," Xavier Becerra says. "Not even the president of the United States." The California attorney general sued the Trump administration Wednesday over the president's proposed border wall, which Becerra says violates myriad environmental laws, the Los Angeles Times reports. “The border between the US and Mexico spans some 2,000 miles," Becerra says. "The list of laws violated by the president’s administration in order to build his campaign wall is almost as long.” According to Reuters, the lawsuit asks a judge to stop all construction on the wall until the federal government ensures it complies with environmental laws and also to tell the Department of Homeland Security it can't circumvent federal guidelines in order to build the wall. The lawsuit claims plans for the border wall include the improper waiver of 37 federal statutes and that federal officials haven't shown that the wall will reduce undocumented immigrants in the San Diego area or that undocumented immigrants are even a major problem in the area. It also claims the Department of Homeland Security violated the Constitution's separation of powers doctrine by allowing the Trump administration to waive state and local laws. Fox News reports the lawsuit is the latest stage in California's war on the Trump administration, which includes a lawsuit over DACA last week, a sanctuary state measure passed over the weekend, and a recent censure against Trump for his comments on neo-Nazis and white nationalists.
