Lawyers for the Trump administration are likely to be in a familiar Oakland, California, courtroom as they seek to defend the president’s declaration of a national emergency at the nation’s southern border with Mexico.

U.S. District Judge Haywood Gilliam Jr. of the Northern District of California on Wednesday was assigned a lawsuit brought by a group of Democratic states’ attorneys general who claim that the declaration will divert funding from the states to finance a wall along the U.S.-Mexico border, a signature proposal of Donald Trump’s 2016 presidential campaign.
