"Stalin would be proud", he added. There are also remarks from a "Grace" and a "Jennifer", as well as appearances by a "Joan" and a "Gaston".
The idea for the video campaign came about after one of Brill's campaign staffers, Jay Ruby, cold-called Gosar's brother David after seeing some of his Twitter posts criticizing his brother, the Phoenix New Times reported.
Brill's ads, of which there are at least three, were filmed in Jackson and Laramie, Wyo.

"I couldn't be quiet any longer, nor should any of us be", Grace Gosar said. David Gosar said that their parents, who are in their 80s, are Republicans and support his brother. Grace begins the ad by telling the camera, "Paul Gosar the congressman isn't doing anything to support rural America".
"I don't really expect it to be much more than a local or perhaps a regional story", he said on Friday, before the ads went viral. More on the family's "massive falling-out" and how Brill recruited them here.
The next month, Gosar said FBI and Department of Justice officials such as Deputy Attorney General Rod Rosenstein, former acting Attorney General Sally Yates, and former FBI Director James Comey should face "treason" charges due to developments in the Russian Federation investigation. "If you can't speak out against your family, then don't be a hypocrite and speak out against someone else's family member". "We all have insane aunts and relatives etc and my family is no different", Gosar wrote.
