Leo C. Donofrio is a retired lawyer and professional poker player. His connection to Obama conspiracy theories is through his lawsuit, Donofrio v. Wells, which challenged the presidential election in New Jersey because the New Jersey Secretary of State (Wells) did not personally verify the eligibility of the candidates for president on the New Jersey ballot, three of whom Donofrio believes were ineligible.
Donofrio maintains a blog site called Natural Born Citizen in which he discusses the case, related cases and citizenship issues.
Donofrio is also a proponent of the argument that President Chester A. Arthur was not a legitimate president because his father was a British citizen when Chester was born. He accuses Arthur of intentionally misdirecting investigators to keep them from discovering his father’s naturalization status. This is discussed here in the article: “The Assassination of Chester A. Arthur“.
After the refusal of Donofrio v. Wells by the United States Supreme Court (and that of another litigant Cort Wrotnowski) Donofrio has taken on a conspiratorial view of things including explaining the Court’s decision as cowardice rather than judicial opinion.
you have no Constitution and you have no “Supreme” court. You have a filthy corrupted snake pit which tried to protect itself from responsibility for this issue by using clerks like brutal praetorian guards.
