A Nevada rancher warned local law enforcement officials on Wednesday to uphold their oaths of office or face the consequences of a people forced to “defend [their] God-given rights,” an ominous message that comes just months after the same rancher led an armed protest against federal agents.

“While the [Bureau of Land Management] was willing to shoot my family over land and power, we were willing to die for our families, our livelihoods and our constitutional rights. You should have been defending these rights for us,” rancher Cliven Bundy‘s son, Ammon, said in a statement addressed to Clark County Sheriff Doug Gillespie. “That’s what we elected you to do. Thankfully, the American people came to our defense. They came to our defense because you failed to do your duty. For that you should be grieved and held accountable for.”
