President Joe Biden used it to help illegal immigrants enter the country. President Donald Trump is using it to help them leave. The contrast between how the two presidents are using the U.S. Customs and Border Protection mobile app couldn’t be starker — and it is exactly what the people voted for.

In addition to releasing over 4 million migrants first caught illegally crossing the southern border, Biden admitted an additional 936,500 migrants through the CBP One app. These migrants did not cross the border illegally but instead made appointments using the app to meet with a CBP officer who, after giving them a cursory background check, released them into the country on “humanitarian” parole.
