Michigans attorney general called for a special prosecutor to probe allegations her Donald Trump -backed opponent led an effort that gained unauthorized access to voting equipment during a hunt for false claims of election fraud after the former president lost the 2020 election.

Attorney General Dana Nessel (D) issued the request Friday after a monthlong investigation by Michigan State Police into potential breaches of voting machines in several counties. The probe began in February amid reports some Trump supporters had convinced clerks to give them access to the machines used in 2020 in an effort to prove voter fraud that cost Trump the 2020 race. There is no evidence of widespread voter fraud, and the former presidents claims have been disproven time and time again.

The investigation, Nessels office said, unexpectedly led to lawyer Matthew DePerno, who officials claim orchestrated a coordinated plan to gain access to voting tabulators.

DePerno is the presumptive Republican nominee in the race and has earned the fierce support of Trump.

When this investigation began there was not a conflict of interest, the petition, first published Sunday by Politico , reads. However, during the course of the investigation, facts were developed that DePerno was one of the prime instigators of the conspiracy.
