12News has learned that some of the Texas Secretary of State investigators watching the general election stopped the voting on three voting machines Monday at the Dishman Elementary polling site in Beaumont. That's just off Walden Road. Those machines were re-calibrated and later returned to service.

Poll workers associated with the Jefferson County Republican Party say voters complained of serious irregularities at several polling locations.

At the Dishman site, voters said they were casting votes for GOP candidates and reviewing the votes to see they had all been changed to Democratic candidates.

12News exclusively reported on the presence of the Secretary of State investigators on our Monday night broadcasts.

We have contacted the Texas Secretary of State's office for further details. Those calls were not immediately returned.

Voters are also complaining of voting machine issues at the John Paul Davis Center. The power also went out at that location.

And complaints have been received from the Port Arthur Public Library voting site, where again a machine is blamed for changing votes to Democratic candidates.
