Why it matters: The unofficial, party-driven recount has been heavily covered on cable news as part of former President Trump's continued effort to sow doubt about the election result.

The findings: "The auditor's final hand count—which quadruple-checked every single one of the 2.1 million ballots—matches Maricopa County's official machine count," Arizona Senate President Karen Fann (R) wrote in a letter to Arizona Attorney General Mark Brnovich on Friday.

She acknowledged the report's validity at a press conference but expressed concern about "less-than-perfect" adherence to Arizona's elections standards as detailed in the report — such as signature verification.

Worth noting: A draft report obtained by The Washington Post and published earlier on Thursday actually gave Biden a slight edge over the official results.

Fann later said that the leaked report was not entirely correct.

Reality check: The Arizona recount "was pilloried by election experts who warned that the methods used by the firm hired to run the review were sloppy and biased," the Post notes.
