At nighttime in a remote region of western Mongolia, Donald Trump Jr. used a rifle with a laser sight to shoot and kill an endangered argali, the largest living sheep. Local hunting guides fanned the lights of their cellphones across the ground to search for where the ram-like creature fell. Trump Jr. asked them not to dismember the animal on the spot, but instead to carry it away on an aluminum sheet to keep its fur and horns intact.

ProPublica described the August excursion in a report that relies on records and interviews to allege that the president’s son received special treatment from the Mongolian government just weeks after U.S. and Mongolian officials met at the White House. The Trump administration has sought to strengthen ties with Mongolia, a longtime defense partner that lies between China and Russia, to prepare for Beijing’s growing global influence.

In Mongolia, permits to shoot and kill an argali, which are prized for their tusks and meat, are determined largely by politics, connections and money, experts told ProPublica. Trump Jr. received a permit after his hunt – which ProPublica reported is a rare occurrence.
