President Trump on Tuesday pardoned a pair of Oregon ranchers whose arson conviction became a focus for opponents of federal government land ownership.

Dwight Hammond, 76, and his son Steven, 49, were convicted in 2012 and sent to prison on arson charges. They had set a series of fires on their ranch that spread to federal land.

The Hammonds' case became the inspiration for the 40-day armed occupation of the Malheur Wildlife Refuge in 2016. The organizers wanted to protest federal land ownership.
