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.

Trump is asking the Supreme Court to let his executive order enabling mass federal layoffs proceed after lower courts blocked it.

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.
