Bundy participated in the 2014 Bundy standoff in Bunkerville, Nevada, in which his father, Cliven Bundy, was the central figure.
The Bureau of Land Management attempted to confiscate Cliven's cattle for grazing on public land for years without a permit.

On April 9, Bundy drove an all-terrain vehicle in front of a Bureau of Land Management truck to block it from leaving.
Officers told him to move his ATV, and he refused, yelling and approaching them belligerently.
When two officers pointed tasers at him and ordered him to back up, Bundy continued to advance.
An officer with a police dog approached to compel him to back away from the officers.
Bundy repeatedly kicked the police dog and was tasered moments later.
He ripped off the taser wires and advanced toward the officers again, resulting in him being tasered a second time.
Bundy acknowledged in an interview that he had also climbed on a dump truck that he believed contained his father's cattle.

On or before April 10, Bundy asked the Oath Keepers to request that their volunteers who came to the protest follow certain rules.
He asked that they not wear military camouflage and to leave their rifles in their vehicles rather than open carry them.
He also asked that they check in with him when they arrived at the protest rally point.
In addition, he asked that they not drive past the rally point to the Bundy ranch.
Furthermore, he asked that no protester give a media interview, instead referring the media to Bundy family members, in particular him, his father, or one of his brothers.

On April 10, Cliven and Ammon were interviewed on air by Fox News' Greta Van Susteren.
Cliven said he would only accept a court order from a Nevada state court, since he believed that a federal court does not have competent jurisdiction.
To that, Ammon added, "If someone came in, busted into my house and abused my children, and so I call the cops, they don't respond, and then I take them to court.
I show up at the courtroom, look on the stand, and it's the very person that abused my children looking down at me in a black robe.
How in the world are we going to get justice in that court?"

On the morning of April 12, The Bureau of Land Management had corralled about 400 of Cliven's cattle.
Ammon and a group of protesters went to the makeshift impoundment site and formed a line across it.
Bureau of Land Management agents called for backup, but were outnumbered, with about 400 protesters compared to the 50 officers present at the scene.
The officers ordered the crowd to disperse over loudspeaker, but they would not.
Instead, gunmen started to gather, causing the officers to retreat.

On April 14, Ammon, along with Cliven and his brother Ryan, were interviewed on air by Fox News' Sean Hannity.
Ammon said, "I'd [participate in the standoff] again, and after it was all over, I couldn't have felt better."
Asked about remarks from Senator Harry Reid that the situation was not over, despite The Bureau of Land Management's withdrawal from the standoff, Ammon responded, "Well, if he doesn't have enough moral fiber in his bones at all to see what happened, that 'We the People' got together and made something right, then I don't think there’s any hope for him, and he needs to be kicked out of office, even if he is the Senate majority leader, it doesn’t matter."
