On April 14, U.S. District Court Judge Dominic Lanza, a Trump appointee, heard Arizonans for Fair Elections v Hobbs, 2:20cv-658. This case was filed by groups supporting various statewide initiatives. They argue that they should be allowed to collect electronic signatures.
The Arizona Republican Party and the Arizona Free Enterprise Club filed amici briefs arguing against the initiative proponents.
