Barr told the AP that U.S. attorneys and FBI agents have been working to follow up specific complaints and information they’ve received, but “to date, we have not seen fraud on a scale that could have effected a different outcome in the election.”
“We have many witnesses swearing under oath they saw crimes being committed in connection with voter fraud. As far as we know, not a single one has been interviewed by the DOJ. The Justice Department also hasn’t audited any voting machines or used their subpoena powers to determine the truth,” he said.
However, Barr said earlier that people were confusing the use of the federal criminal justice system with allegations that should be made in civil lawsuits. He said a remedy for many complaints would be a top-down audit by state or local officials, not the U.S. Justice Department.
“There’s a growing tendency to use the criminal justice system as sort of a default fix-all,” he said, but first there must be a basis to believe there is a crime to investigate.
“Most claims of fraud are very particularized to a particular set of circumstances or actors or conduct. ... 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.”
