Fulton County, Pa., has filed a lawsuit against Dominion Voting Systems over what it claims are “severe” issues with voting data discovered after the 2020 election.

County officials claims that a report from earlier this month revealed that “security measures necessary to harden and secure” Dominion’s systems had not been performed, that “external USB hard drives had been inserted in the machines on several occasions,” and that “there is no known list of approved external drives that could have been or were used or inserted into the machines.”

The suit also alleges the county discovered a “python script” had been installed on one device, and that that same device was “connected to an external device on an external network,” reportedly one linked to Canada.
