Exactly right.
Trump should quickly reactivate the Bracero Program to legally bring in guest workers for the repairs. That would silence the critics, get the rebuilding done, and show how to do it legally.
Are you f'ing nuts? The Bracero program was a disaster and set the stage for an invasion of illegal aliens from Mexico. Operation Wetback was part of our response. The Mexicans who came in thru the program did not leave and brought in their relatives. Guest workers don't go home. Ask Germany about its gastarbiters that brought in millions of Turks.
