The Biden administration is suing Arizona Republican Governor Doug Ducey over his state’s illegal construction of a makeshift wall along the U.S.-Mexico border, built with double-stacked shipping containers and razor wire. The complaint filed by the Justice Department demands Arizona halt construction and remove the barrier, which immigration and environmental advocates say is destroying precious biodiversity in the Sonoran Desert and putting the lives of asylum seekers at further risk as they attempt to cross to the U.S. for refuge. Ducey has said his administration was trying to fill up the gaps in former President Trump’s unfinished border wall. The lawsuit comes less than three weeks before Ducey leaves office on January 2.
