I have no idea how to find it but at various times people have posted here at FR news articles from his past referring to him as the “African-born senator from Illinois”. Several, from a variety of publications.
Which doesn’t mean he was born in Africa but does mean at one time it suited him for people to think he was born in Africa. Gave him a patina of exotic, perhaps, made him more interesting than he was.
Then when it no longer suited him to be known as “african born” all that disappears and now if you take him at his (former) word, you’re the crazy one.
Early in our search there were several. Some disappeared before we could capture or send to others. As we searched they became fewer and then only in off shore publications. Personally found three: Two in African article and one in Indonesia.
At one time there was a CSpan video/Alan Keyes. Then it too was edited out. The Way-Back machine SHOULD have a plenty of such articles.
