WaPo:

Current and former election administrators said it would be virtually impossible for a foreign country to produce and mail in phony absentee ballots without detection, an issue Attorney General William P. Barr raised as a serious possibility in an interview published Monday.

Barr told the New York Times Magazine that a foreign operation to mail in fake ballots was “one of the issues that I’m real worried about.”

“We’ve been talking about how, in terms of foreign influence, there are a number of foreign countries that could easily make counterfeit ballots, put names on them, send them in,” Barr said. “And it’d be very hard to sort out what’s happening.”

Barr did not offer any evidence of how such a scenario would take place.

Elections officials in multiple states said it would be virtually impossible for a foreign government to achieve what Barr described.
