Gosar's family stepped up during the 2020 election to beg Arizonans not to vote for their brother.
"The Democrat challenging Gosar in Arizona's 4th District unveiled a new ad Friday that features Grace, David, Jennifer, Tim, Joan and Gaston lambasting Gosar over Social Security, health care, water policy and more," said CNN about the ad Gosar's siblings did for Democrat Delina DiSanto.
In previous years, Gosar's brother David warned that their brother may not be mentally stable.
"We know him to be an extremist and we took that very seriously," said sister Jennifer Gosar, who now lives in Seattle. "I believe that my brother has been a constant perpetrator of misinformation. ... I've been incredulous at the lack of accountability thus far. I would think Wednesday would be certainly a line."
"He's set a dangerous sort of precedent along the ten years he's been in office," said brother Tim Gosar, who lives in Fort Collins, CO. "When you talk about what happened the other day, you're talking about treason. You're talking about overthrowing the government. That's what this is. If that doesn't rise to the level of expulsion, what does?"
