Is suspected Spokane arsonist Aaron F. Farinacci a registered Republican voter? No, that's not true: Voters in Washington state do not register by political party, according to the Washington Secretary of State's office. Voters in the state can become members of any political party by contacting the party directly, but they are not "registered" as members of a party when they register to vote. The Secretary of State's office also said it did not have a voter registered under that name.
The claim appeared in a post (archived here) by the @chiweethedog account on X on Aug. 3, 2026. It read:
Right wing registered Republican voter, Aaron F. Farinacci, 37, Spokane, WA arrested on arson charge.
This is what a screenshot of the video in the post looked like at the time of writing:
