WASHINGTON (Reuters) - U.S. Attorney General William Barr said on Wednesday that mail-in ballots for the Nov. 3 election could be vulnerable to fraud, echoing an argument President Donald Trump has made to denounce the use of voting by mail.

"People trying to change the rules to this methodology, which, as a matter of logic, is very open to fraud and coercion. It's reckless and dangerous, and people are playing with fire," Barr said in an interview with CNN.
