Novità sul muro sul confine tra Stati Uniti e Messico. Il Presidente Donald Trump lo vuole alto circa 9 metri, una struttura esteticamente gradevole se la si guarda dal lato nord quantomeno e soprattutto difficile da scavalcare o "tagliare". Questi i parametri fissati per la gara d'appalto per la sua costruzione, comparsi sito web dell'agenzia che fa capo al Dipartimento per la Sicurezza Interna.
Le proposte dovranno pervenire entro il 29 marzo. I parametri sono tuttavia variabili, risulta infatti che se alcuni dei requisiti parlano di un vero e proprio muro di cemento, altri sembrano considerare anche la possibilità che venga realizzata una struttura trasparente.
