In addition to step-grandmother Sarah's statement about witnessing the birth in Kenya (as sworn to in the case on which Philip Berg was working), there are Kenyan government officials who have stated that Obama was born in that country:
The Kenyan Ambassador to the United States said precisely that in an interview on a Detroit FM radio station on the day after Election Day in 2008.
At least three different Kenyan parliamentarians have stated in the Parliament's minutes that Obama was born in Kenya.
Obama's birth in Kenya has also been asserted in several distinct articles in English language African newspapers.
Anyone out there asking why no one in Congress is willing to ask for an investigation?
Thanks for the pings justiceseeker93, grey_whiskers, and LucyT.
