The more we learn about the true dimensions of the crisis at the U.S.-Mexico border, the worse it is.

A new report says that in the last few months, U.S. authorities have encountered illegal border crossers not just from Mexico, or the Northern Triangle countries of Guatemala, El Salvador, and Honduras, but from 160 nations around the globe. People are coming to Mexico from the most distant spots on the planet in order to cross illegally into the United States, confident that President Joe Biden will let them stay. And Biden is doing just that.
