A top Republican lawmaker in Pennsylvania is seeking to access voting machines and election data in three counties for forensic investigation of the 2020 election and 2021 primary, but at least one county refused the request.

Sen. Doug Mastriano (R-P.A.), chairman of the Intergovernmental Operations Committee, sent letters to Philadelphia, York, and Tioga counties last week requesting election materials to conduct an Arizona-style inquiry looking for evidence of fraud, according to the Washington Examiner.

However, three commissioners in Tioga County decided not to offer up its voting machines for review after Pennsylvania’s acting Secretary of State Veronica Degraffenreid sent directives advising counties against giving “third-party entities” access to their materials or they’d risk decertification.

According to Degraffenreid’s directive, issued on July 8, “County Boards of Elections shall not provide physical, electronic, or internal access to third parties seeking to copy and/or conduct an examination of state-certified electronic voting systems, or any components of such systems, including but not limited to: election management software and systems, tabulators, scanners, counters, automatic tabulating equipment, voting devices, servers, ballot marking devices, paper ballot or ballot card printers, portable memory media devices (thumb drives, flash drives and the like), and any other hardware, software or devices being used as part of the election management system.”

The directive also said that Pennsylvania “will not reimburse any cost of replacement voting equipment for which certification or use authority has been withdrawn pursuant to this directive.”

In a reply, Tioga County’s solicitor Christopher Gabriel said Wednesday, July 14 that, “We can’t be in a position where we don’t have the election machines because we have to run the next election, these are extremely expensive machines, and our position is we need to follow the direction that [Degraffenreid] has given us.”

Tioga County was won by former President Donald Trump in the November election.

In his letter, Mastriano set a deadline of July 31, threatening to pursue subpoenas if they do not comply. He said other counties could be added depending on what is found in the investigation.

The senator has also criticized Gov. Tom Wolf’s administration for their obstruction attempts and pledged to press forward with the audit.

Trump lost the state of Pennsylvania by a little more than 80,000 votes, or 1 percentage point, to President Joe Biden.
