The U.S. government has granted waivers to let 872 refugees into the country this week, despite President Donald Trump's executive order on Friday temporarily banning entry of refugees from any country, according to an internal Department of Homeland Security document seen by Reuters.

A Homeland Security official, speaking on condition of anonymity, confirmed the waivers, noting that the refugees were considered "in transit" and had already been cleared for resettlement before the ban took effect.

Refugees preparing for resettlement typically have severed personal ties and relinquished their possessions, leaving them particularly vulnerable if their plans to depart are suddenly canceled.
