Arizona governor builds border wall of shipping crates in final days of office

Critics say Republican Doug Ducey's scheme is illegal because makeshift barrier is being erected on tribal and federal land

A makeshift new barrier built with shipping containers is being illegally erected along part of the US-Mexico border by Arizona's Republican governor - before he has to hand over the keys of his office to his Democratic successor in January.

Doug Ducey is driving a project that is placing double-stacked old shipping containers through several miles of national forest, attempting to fill gaps in Donald Trump's intermittent border fencing.
