In 2023, Americans for Prosperity challenged the constitutionality of Arizona ballot measure Proposition 211. That measure, misleadingly advertised as requiring disclosure of large contributions for political advertising, actually creates an expansive state reporting network of supporters to issue advocacy campaigns — including potential disclosure of individuals who had no knowledge of the communications they supposedly support.
This framework chills the First Amendment speech and associational rights of anyone looking to speak about issues in Arizona.
