Tina Peters, a former Colorado election official, was released from a Colorado prison on Monday after her sentence was commuted by the state's Democratic governor, Jared Polis.
Peters was serving a nine-year prison sentence for her role in a breach of election equipment in Mesa County, Colorado, but her sentence was reduced to 4 ½ years in May.
Prosecutors argued that Peters unlawfully facilitated access to secure voting-system data, but she and her supporters maintained that she was attempting to expose vulnerabilities in election systems.
Peters, a Republican, served 20 months of her original nine-year sentence before being released.
Her release has been met with criticism from Colorado's secretary of state, Jena Griswold, who denounced the decision, saying it would "embolden the election denier movement."
Peters has been a vocal supporter of election conspiracy theories and has promoted false claims about voting machines.
