SAN RAFAEL VALLEY, Arizona (AP) — Work crews are steadily erecting hundreds of double-stacked shipping containers along the rugged east end of Arizona’s boundary with Mexico as Republican Gov. Doug Ducey makes a bold show of border enforcement even as he prepares to step aside next month for Democratic Governor-elect Katie Hobbs. Ducey ordered the containers to fill open spaces on the border wall that former President Donald Trump promoted to stop people from crossing illegally. It’s unclear what Hobbs will do. Federal agencies say Arizona is violating U.S. law and environmental groups say the containers could imperil natural water systems and endangered species. (Photo: AP)
