The story of how Republicans decided to oust Harris — marking only the fourth time in history that an Arizona state House member has been expelled — illuminates what it takes for GOP lawmakers to police their own when it comes to election-related misinformation.

Even given the extreme nature of the false claims, those alone would not have been enough to merit expulsion from the Republican-led House, according to interviews with 18 lawmakers, staff, local leaders and political operatives.

Instead, they said, she was done in both by her dishonesty with colleagues about whether she knew in advance the substance of her witness’s planned testimony as well as her willingness to help spread conspiracy theories targeting her party’s own leaders.

“There’s a lot of election deniers out there,” said one key state House Republican who spoke on the condition of anonymity to share a candid assessment of a GOP caucus in which election denialism is common. “If that’s what we were going to be doing, there would be, like, 10 people expelled by now.”
