Saying it'll stem an "invasion" of illegal drugs and immigrants, President Donald Trump declared a national emergency to fund his southern border wall on Friday, sparking a constitutional battle with Congressional Democrats. He also signed a spending bill --- devoid of wall funds --- to avert another government shutdown. Presidents have declared 58 emergencies, often to impose international embargoes, since a 1976 law enabled them.
Will it stand? The Democrat-controlled House is investigating its propriety, states are suing and so are Texas land owners. Trump said he anticipated lower federal courts would side with challengers, but "we'll win in the Supreme Court."
