FILE - In this April 12, 2014, file photo rancher Cliven Bundy, top center, addresses his supporters along side Clark County Sheriff Doug Gillespie, right, while being guarded by self-described militia members in the foreground. Twice federal prosecutors in Las Vegas have failed to win full convictions of men who had guns during an April 2014 armed standoff with government agents trying to round up cattle belonging to Nevada rancher Cliven Bundy. Nevertheless, they're now moving to the main event, with openings expected Tuesday, Nov. 7 for a trial of the 71-year-old family patriarch and states' rights figure, his two eldest sons and one other co-defendant accused of leading a self-styled militia in an uprising against government authority.
