And the DHS and DOJ have looked into that, and so far, we haven’t seen anything to substantiate that,” Barr said.
He said people were confusing the use of the federal criminal justice system with allegations that should be made in civil lawsuits. He said such a remedy for those complaints would be a top-down audit conducted 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, and people don’t like something they want the Department of Justice to come in and ‘investigate,’” Barr said.
He said first of all 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. 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.”
