Republican election audits have led to voting system breaches, experts say

MyPillow chief gave out election software at South Dakota event derived from Republican challenges in Colorado and Michigan

Republican efforts to question Donald Trump's defeat in 2020 have led to voting system breaches experts say pose a risk to future elections.

Copies of Dominion Voting Systems softwares used for designing ballots, configuring voting machines and tallying results were distributed at an event this month in South Dakota organized by the MyPillow chief executive, Mike Lindell, a Trump ally who has made unsubstantiated claims about last year's election.
