The U.S. Supreme Court swept away this week another obstacle to one of President Donald Trump's most aggressively pursued policies - mass deportation - again showing its willingness to back his hardline approach to immigration.

The decision lets the Trump administration halt, for now, a program that lets migrants from Cuba, Haiti, Nicaragua and Venezuela live and work in the U.S. for up to two years.

An appeal that landed at the Supreme Court Tuesday could test the justices’ emerging concern about President Donald Trump’s aggressive deportation policies and whether he is willing to defy judicial orders.
