Trump emergency declaration faces fights in the courts

President Donald Trump declared a national emergency along the southern border and predicted his administration would end up defending it all the way to the Supreme Court. That might have been the only thing Trump said Friday that produced near-universal agreement. House Speaker Nancy Pelosi and several Democratic state attorneys general already have said they might go to court. The coming legal fight seems likely to hinge on two main issues: Can the president declare a national emergency to build a border wall in the face of Congress' refusal to give him all the money he wanted and, under the federal law Trump invoked in his declaration, can the Defense Department take money from some congressionally approved military construction projects to pay for wall construction?
