The BNA in the UK have discovered some archived files where they found that an unnamed son of Barack Obama Sr. who was born in Kenya in 1961. It does show the birthdate of the “unnamed” son which is Aug. 4th, 1961 (Obama’s birthday). It doesn’t show Obama Jr.’s name, though so that is not really official proof… but it’s a hint that the “unnamed” son could be Obama Jr., though.
Damn…. Obama Sr. and Ann Dunham hid his info VERY WELL.
