President Donald Trump has pardoned two Oregon cattle ranchers whose sentence for arson led armed militiamen to seize control of a wildlife refuge in 2016. Dwight Hammond, 76, and his son Steven Hammond, 49, were convicted in 2012 after a prescribed burn on their land spread to nearby public lands. The pair served time in jail, but a judge later ruled that they must serve their full five-year sentence. The ruling sparked anti-government protests that left one rancher dead. The case had drawn the attention of limited-government proponents, including the family of Nevada rancher Cliven Bundy who was himself facing charges relating to an armed standoff with law enforcement. His son, Ammon Bundy, then began a social media campaign backing the Hammonds, and travelled to Burns, Oregon, to organise protests calling for their release. On 2 January, 2016 [Mr Bundy and his group] took over the Malheur National Wildlife Refuge and widened the range of demands. The standoff ended when police arrested several members and fatally shot the group's spokesman, LaVoy Finicum. The Obama administration insisted the Hammonds receive a mandatory minimum sentence of five years - but Mr Trump has other ideas. Tuesday's announcement marks seven pardons by Mr Trump, as well as two commuted sentences. Last month, Mr Trump granted clemency to 63-year-old Alice Johnson after meeting with celebrity Kim Kardashian, who lobbied the president for her release.
