From January 2 to February 11, 2016, the headquarters of the Malheur National Wildlife Refuge (MNWR) in eastern Oregon were seized and occupied by an armed group, later called Citizens for Constitutional Freedom, affiliated with private U.S. militias and the sovereign citizen movement following an earlier peaceful march in protest of the prison sentences for ranchers Dwight Hammond and his son, Steven Hammond, who were convicted of arson on federal land, sentenced to five years' imprisonment, and sought clemency from the U.S. president. The occupation received widespread coverage from media outlets.
