Van Tatenhove has lived in Colorado for a long time and formerly had a tattoo shop.
He encountered the Oath Keepers in 2014, shortly after moving to Montana while reporting the Bundy Ranch story.
The Oath Keepers joined others in supporting Nevada rancher Clive Bundy, who earned national recognition after refusing to pay federal government fees.
Bundy owed the fees because his cattle were grazing on public land close to his own.
Jason Van Tatenhove children: Who are his two daughters?
He married, had children, and founded a tattoo shop in Fort Collins.
He closed the store in 2013 and relocated his family to Butte, Montana. He and his family wanted to live in a more rural setting and learn more about farming, he explained.
When the government stated that it would confiscate his livestock, Bundy called on armed Americans to come to his aid.
The government finally caved, and the Oath Keepers, who were founded in 2009, earned popularity as a result of the incident.
During the stalemate, Van Tatenhove impressed Rhodes and was shortly employed.
