Dominion Voting Systems’ electronic voting machines contract with the U.S. territory of Puerto Rico is under threat after contentious primaries produced upset results. According to election officials, some machines reported zero votes for certain candidates or reversed count totals. Counts reported by machines were also sometimes lower than paper counts.

“The concern is that we obviously have elections in November, and we must provide the [island] not only with the assurance that the machine produces a correct result but also that the result it produces is the same one that is reported,” said Jessika Padilla, interim president of Puerto Rico’s elections commission. She attributed the issues to problems in the machines’ software.
