Trump's travel ban faces US Supreme Court showdown

Case represents a test of limits of power of the president

WASHINGTON - The first big showdown at the US Supreme Court over President Donald Trump's immigration policies is set for Wednesday when the justices hear a challenge to the lawfulness of his travel ban targeting people from several Muslim-majority countries.

The case represents a test of the limits of presidential power. Trump's policy, announced in September, blocks entry into the United States of most people from Iran, Libya, Somalia, Syria and Yemen. Chad previously was on the list but Trump lifted those restrictions on April 10.
