I had a link from Cynwoody, but it's gone missing.
The post relied on reporting from a Hillary-favorable website and was concerned with Chester A. Arthur's father being born in Great Britain (true) -- therefore, Arthur had been ineligible.
Chester A. Arthur was indeed ineligible, but no one could prove it at the time. He took great pains to hide the truth.
Cmdr. Kirchner and Donofrio were writing about it before the usurper was installed by the uniparty.
