NBC: LAS VEGAS — A U.S. judge in Nevada declared a mistrial Wednesday in the case against a states’ rights figure, his two sons and another man accused of leading a 2014 armed standoff with federal agents during a cattle grazing dispute.

Chief U.S. District Judge Gloria Navarro in Las Vegas dismissed a jury seated last month for the long-awaited trial of Cliven Bundy, his sons Ryan and Ammon Bundy and self-styled Montana militia leader Ryan Payne.

It is the latest in a string of failed prosecutions in Nevada and Oregon against those who have opposed federal control of vast swaths of land in the American West.

Jurors in Portland, Oregon, acquitted the two Bundy sons of taking over a U.S. wildlife refuge in Oregon for more than a month in early 2016 amid calls for the U.S. government to turn over public land to local control.

In the Nevada case, Navarro faulted federal prosecutors for failing to turn over all evidence to defense attorneys, including records about the conduct of FBI and Bureau of Land Management agents during the standoff. read more
