In an interview with The Associated Press, Barr said U.S. attorneys and FBI agents have been working to follow up specific complaints and information they’ve received, but they’ve uncovered no evidence that would change the outcome of the election.

“To date, we have not seen fraud on a scale that could have affected a different outcome in the election,” Barr told the AP…

“There’s a growing tendency to use the criminal justice system as sort of a default fix-all, and people don’t like something they want the Department of Justice to come in and ‘investigate,’” Barr said…

“Most claims of fraud are very particularized to a particular set of circumstances or actors or conduct. They are not systemic allegations and. And those have been run down; they are being run down,” Barr said. “Some have been broad and potentially cover a few thousand votes. They have been followed up on.”
