"It's is intervention time and intervention time means that you go to vote and you go to vote Paul out", Tim Gosar said.
It is not the first time that some of Gosar's nine siblings have banded together to speak out against their brother. "This is not who we are".

Brill told the newspaper that while Paul's siblings are 'really upstanding, wonderful people, ' he has not yet met them and was not involved in the making of the ads so that he would not influence their testimonials. And David says he's disappointed in the other three siblings who didn't stand with them for the advertisement.
He faces an uphill battle for the seat; Gosar trounced his Democratic opponent in the deep-red district in 2016, receiving 71.5 per cent of the votes. Gosar has been supportive of President Donald Trump.
He said he's also upset by people who tell him that there's something wrong with breaking with his family or who make the situation into a joke. "This is causing serious damage to the country", he said.
But what if those family members wanted nothing to do with you?
