The Supreme Court on Thursday cleared the way for the Trump administration to deport to South Sudan a group of migrants that have been held for weeks on a military base in Djibouti.

The Supreme Court is clearing the way for the deportation of several immigrants who were put on a flight in May bound for South Sudan, a war-ravaged country where they have no ties.
