MADISON, Wis. (AP) — The Wisconsin Elections Commission says it is confident that voting machines in St. Croix County that had broken warranty seals are accurately tabulating and reporting results there.

The commission issued a statement Tuesday explaining why some of the machines had broken seals. It included an affidavit from a technician saying he broke them to service modems on the scanners.

The news comes as election officials across the state are recounting results from the presidential race at the request of Green Party candidate Jill Stein.

The commission says Stein’s campaign had representatives on site who verified the accuracy of ballots fed through the machines.

St. Croix County reported after the recount that Donald Trump gained one vote over Hillary Clinton. The recount is ongoing statewide.
