A grand jury on March 27 authorized and requested the hiring of an expert to conduct an investigation of voting machines from Hidalgo County’s Democratic primary, said Hidalgo County Criminal District Attorney René Guerra.

Guerra explained that some voters filed complaints with the election department regarding the election, and some candidates raised concerns about the election in a letter to the county judge. Guerra then became involved in his role to “investigate crimes,” and he went to the grand jury for help.
