The threats are a continuation of a prolonged campaign from Trump to tackle illegal immigrants entering the United States, a centerpiece of his presidential campaign promise. But if a shutdown blocks trade, too, it would disrupt the daily flow of $1.7 billion of goods to store shelves and factory floors.
"Shutting down the border would be devastating for the entire country", said Jon Barela, CEO of the Borderplex, a binational and regional trade organization focused on Las Cruces, N.M., El Paso and Ciudad Juárez, Mexico.
Margo singled out 2008 legislation that he says made it easier for migrants to seek asylum at the southern border, which in turn has overwhelmed immigration enforcement resources.

"Wait times in Brownsville [Texas] were around 180 minutes, which were two times the peaks of past year", said a senior DHS official on a call with reporters.
"We've had a fence for 10 years and it has impacted illegal immigration and curbed criminal activity", Margo stated.
