On December 12, 2020, Gretchen Jacobs, one of Arizona's most powerful and well paid lobbyists, sent a message to White House staffer Stephanie Grisham that she had spoken with Fann and “asked her what would cause her to withhold the electors” needed to certify the results.

[10] The following day, on December 15, 2020, Fann she and Senator Eddie Farnsworth were issuing subpoenas for the scanned ballot images and a forensic audit of all voting machines used in the 2020 election.

[11] In April 2021, Fann ordered an audit of the election results in Maricopa County, hiring a firm that was founded by a pro-Trump conspiracy theorist who promoted false claims of fraud.

[13] The Arizona Secretary of State, Katie Hobbs, criticized the audit for lax chain of custody procedures, calling it "a significant departure from standard best practices.

"[16] After her criticism of its procedures resulted in her receiving death threats, the Arizona Department of Public Safety assigned a security detail to guard Hobbs and her staff.

[21] The United States Department of Justice (DOJ) sent a letter to Fann that expressed concerns that the audit could violate federal laws regarding ballot custody and voter intimidation.

Republican board chairman Jack Sellers stated that the allegations were actually due to the incompetence of the auditors and accused Fann of an "attempt at legitimatizing a grift disguised as an audit.

"[29][30] After consulting with the United States Department of Homeland Security and the Election Assistance Commission about the machines used to tabulate the ballots that were turned over in response to the Senate subpoena, Hobbs concluded that the equipment had been compromised and became impossible for the county alone to recertify for future use.

[32] A preliminary report on the results of the audit, despite the expenditure of some six million dollars raised from Trump supporters determined to overturn the election, found no evidence of fraud.
