Jerome Corsi, who wrote “Obama Nation: Leftist Politics and the Cult of Personality,” had planned to launch his far-right tract in the Kenyan capital Nairobi on Tuesday.
However, immigration officials intercepted him as he arrived at a luxury hotel where the launch event was due to take place.
This is the second time Dr. Corsi has been involved in an effort to question the credentials of the Democratic presidential candidate. The episode also underscores the depth of support for Senator Obama in Kenya.
His book has angered many ordinary Kenyans who view Obama – the son of a Kenyan goat herder who grew up to become a government economist – as a hero.
It questions Obama’s fitness to hold office, rakes over his family history, and explores alleged links with the Kenyan prime minister, Raila Odinga.
“Our passports and visas are in order but it seems the Kenyan authorities have lost our arrival cards, which we filled in on the plane coming here,” he said. “So we will leave while they complete their investigations, but have been told we can return.”
As well as launching his book, Corsi planned to visit Obama’s half-brother George, who was recently found to be living in squalid conditions in a Nairobi slum.
