NEW YORK — It might seem like family dysfunction or a bad case of sibling rivalry.
Six of nine brothers and sisters of Representative Paul Gosar, Republican of Arizona, publicly endorsed his Democratic opponent in the midterm elections in videos Friday, in what one of them said was nothing short of a moral imperative.
The siblings were alarmed at what they saw as the congressman’s increasingly extremist views on immigration, health care and white supremacists, one of them, David Gosar, said Saturday.
“I’m just hoping either in this election cycle or next, the people get the idea that he’s just not fit for that office and he needs to be removed,” he said.
The Democratic candidate, Dr. David Brill, released the videos, drawing astonishment at the rare public display of a family fighting over political views (although it was not the first time this year) as well as jokes about what a Gosar Thanksgiving gathering might be like.
The videos show the siblings attacking Paul Gosar on health care and Social Security, among other issues, and expressing disdain for him.
Brill said there were more videos to come, although he wouldn’t specify how many.
David Gosar, a lawyer in Wyoming, identifies as a progressive, although he said he is not a registered Democrat. Three of the siblings have donated to the Democratic candidate’s campaign, Brill said.
Paul Gosar did not respond to requests Saturday for comment, but in a series of tweets Saturday afternoon, he wrote, “You can’t pick your family.”
“My siblings who chose to film ads against me are all liberal Democrats who hate President Trump,” he wrote.
He then called his siblings “disgruntled” supporters of Hillary Clinton, saying they “are related by blood to me but like leftists everywhere, they put political ideology before family. Stalin would be proud.”
He added: “To the six angry Democrat Gosars — see you at Mom and Dad’s house!”
Reached at her home in Wyoming, Bernadette Gosar, the siblings’ 85-year-old mother, said she was unaware of the videos until she was contacted by The New York Times. Once they were described to her in detail, she said she was “shocked” and “crushed.”
She said that she had a “wonderful family,” but that the Gosar children in the videos did not relate politically to Paul Gosar or herself. She said from what she knew about Brill, “He doesn’t have a chance.”
“I share the same philosophy and policies that Paul does,” she said. “He’s done a hell of a job for Arizona, and they love him.”
Gosar first won election in 2010, his first foray into politics, with the support of the Tea Party.
The congressman’s brother David caught the eye of Brill’s campaign through his criticism of Paul Gosar on Twitter. David Gosar said he keeps the Twitter account solely to publicly admonish his brother, alternately referring to him as “Wease” or “Weasel.”
He said a staff member on Brill’s campaign called him and delved deeper into the familial rift and then asked the siblings to be in the campaign videos. Brill said the effort was “collaborative.”
“This is the Gosar siblings coming forward for the good of our country,” he said.
The Brill campaign said the siblings were not paid.
Paul Gosar is known as an immigration hard-liner. Earlier this year, he called for authorities to check the immigration status of those attending the State of the Union address, and arresting and deporting “any illegal aliens attempting to go through security.”
Seven brothers and sisters had previously written a letter to a local Arizona newspaper, the Kingman Daily Miner, condemning their brother’s suggestion in a Vice News interview in October that the white nationalist rally in Charlottesville, Va., was backed by George Soros, the billionaire who is a donor to liberal causes.
Gosar previously suggested Soros was a Nazi collaborator during World War II.
“It kept building and building,” David Gosar said. “He’d just keep getting nuttier and nuttier.”
It wasn’t always that way. He said the 10 siblings were tight-knit growing up in a small town in Wyoming, playing sports or cards.
“It was absolutely a blast,” he said.
As the siblings moved to different parts of the country and started families of their own, they met less frequently but still talked on the phone, he added. Then Paul Gosar, the eldest sibling, started gearing up to run for Congress in 2010 and said that he believed, incorrectly, that President Obama was born outside the country.
That was the last time the two of them spoke, David Gosar said. Attempts to reach the other Gosar siblings were unsuccessful Saturday.
One of the attack videos is titled “A Family Defends Its Honor.” David Gosar opens it by saying, “None of this is pleasant for any of us,” after which several siblings say that their decision to endorse Brill was “horrible” and “difficult” and that it “brings sadness.”
“I think my brother has traded a lot of the values we had at our kitchen table,” said Joan Gosar, a civil engineer.
“It’s intervention time,” said Tim Gosar, a private investigator. “And intervention time means that you go to vote and you go to vote Paul out.”
Another video is titled “Paul Gosar Is Not Working For You,” in which Grace Gosar says, “Paul Gosar the congressman isn’t doing anything to help rural America.” A third video criticizes Paul Gosar’s stance on health care.
What impact the videos will have was unclear. The Cook Political Report rated the district as solidly Republican, and Gosar won the district in 2016 with more than 70 percent of the vote.
David Gosar said he could see a world where he would be proud of a changed Paul Gosar.
“I don’t expect anything like that from him,” he said.
