A Democrat running against Arizona Representative Paul Gosar unveiled a powerful series of ads on Thursday that feature six people who denounce Gosar and endorse his rival.

They're Gosar's siblings.

The conservative congressman's family members' video testimonials, which will air on TV soon, are in support of David Brill, a Democrat hoping to unseat Gosar in Arizona's Fourth Congressional District.

The campaign revealed the ads at a fundraiser held at First Studio in Phoenix on Thursday evening. In them, six of Gosar's siblings – Tim, Jennifer, Gaston, Joan, Grace, and David – say that their brother's positions on immigration, the environment, and health care have effectively torn their family apart. They condemn their brother in striking terms.

In one video, Grace Gosar says, "It would be difficult to see my brother as anything but a racist."
