Warren Petersen

There are no reports of Warren Petersen being convicted of, charged with, or indicted for criminal fraud, bribery, or personal financial misconduct in his career. His career has been marked by significant political and legal controversy regarding the 2020 election. Petersen, as Senate President, oversaw a partisan review of Maricopa County’s 2020 election conducted by Cyber Ninjas, which ultimately confirmed Joe Biden’s victory. In 2026, he complied with a federal grand jury subpoena related to an ongoing investigation into efforts to overturn the 2020 election. Subsequently, he publicly referred Arizona Attorney General Kris Mayes and Secretary of State Adrian Fontes to the Department of Justice, alleging they committed obstruction of justice and witness tampering by advising county officials not to comply with federal records requests. Additionally, Petersen has faced judicial scrutiny regarding legislative privilege. Courts have rejected his attempts to avoid depositions and document production in cases involving voting legislation and claims of discriminatory intent. Other controversies involve his use of legislative procedures to stall gubernatorial nominees, efforts to overturn federal land designations and environmental regulations, and receipt of PAC funding from a company currently being sued by the Attorney General’s office.
