The CBP One app, a government platform that the Biden administration used to admit more than 740,000 immigrants into the United States, was shuttered within moments of President Donald Trump taking office this afternoon.

The CBP One App, used by migrants to notify the U.S. government of their intention to arrive at a port of entry and provided resources, has been shut down by the Trump Administration.

President Donald Trump on Monday officially shut down the Customs and Border Protection-run app designed to help schedule appointments for people seeking eligibility for asylum, closing off a pathway for migrants at the Southern border hoping to enter the United States.
