California suing Trump administration over border wall

‘The US state of California has filed a lawsuit that will challenge President Donald Trump’s proposal to build a wall along the US-Mexico border, a project the state’s attorney general has called “medieval.”
The lawsuit filed Wednesday alleges that the Trump administration has failed to comply with federal and state environmental laws, relied on federal statutes that do not authorize the proposed projects and violates the US Constitution’s separation of powers doctrine.
The lawsuit also says the US Department of Homeland Security decided to build the wall without complying with the Clean Water Act and National Environmental Policy Act, hence the 2,000-mile-long (3,218 km) project lacks proper environmental measures.
“They’re violating the Tenth Amendment and infringing on a lot of state laws, not just federal laws, that effect our state. At the same time, they’re trying to do something that only Congress can do,” California Attorney General Xavier Becerra told journalists in Washington in advance of an official announcement he plans to make in San Diego Wednesday.’
