The striking part? It's not their brother.
Siblings of Arizona Republican Representative Paul Gosar have denounced their brother's views and endorsed his rival in a video campaign for Democratic candidate David Brill launched Thursday.
At a Capitol Hill hearing for former Federal Bureau of Investigation official Peter Strzok, Gosar also memorably said that his job as a dentist made him particularly skilled at reading body language. "Paul's absolutely not working for his district", says a lawyer whose name is shown as "David".
"If he actually cared about people in rural Arizona, I bet he'd be fighting for Social Security, for better access to health care".
"It's intervention time. And intervention time means that you go to vote, and you go to vote Paul out", says Tim Gosar, a private investigator. The videos feature six of the 10 Gosar children, who are originally from Wyoming: Tim, Joan, Grace, David, Jennifer, and Gaston.
Local paper the Arizona Republic calls it "brutal, but not unexpected".
The siblings previously condemned the congressman's false accusation in 2017 that wealthy Democratic donor George Soros was a Nazi collaborator in World War II.
The letter went on to say that 'It is extremely upsetting to have to call you out on this, Paul, but you've forced our hand with your deceit and anti-semitic dog whistle. He criticised the pontiff's support for climate change, calling it "questionable science" deployed "to guilt people into leftist policies".
In July 2018, Gosar appeared at a rally in the United Kingdom in support of far-right political activist Tommy Robinson.
The six siblings who chose to appear in the ad are ripping him saying their brother has destroyed the family name.
In another video, Gosar's sister Grace says, "It would be hard to see my brother as anything but a racist", according to the Phoenix New Times.
So far, Gosar has not responded to the ad. The Republican, who won his district with 71% of the vote in 2016, is still considered likely to keep the seat he has held since 2011.
Gosar is a close ally of the Trump administration who has cheered on the crusade against top Justice Department and Federal Bureau of Investigation officials.
