Overfield claims to have been out of politics for 15 years when he decided to become active again. When he joined the Reform Party of Canada, he claims to have "let the Reform Party executive know about his political past, and they had no problems with it." Overfield stated that Reform Party member Harry Robertson admitted him to the Party and that future Prime Minister of Canada Stephen Harper was well aware of Overfield's past involvement in far right groups. Harper denied such knowledge and stated that he had been "building issues into the Reform Party's platform to actively discourage extremists and 'nut cases'" at the time of Overfield's membership.
