He had been an extremely bright student and 1958 he was awarded an American sponsored scholarship in economics to the University of Hawaii at Manoa. In 1959, at the age of 23, Obama Sr. became the first African student enrolled at the University of Hawaii at Manoa. Kezia, now pregnant, remained in Kenya. She and Obama Senior would have two more children in subsequent years.

Stanley Ann, still 17 years of age, began classes in the fall of 1960 at the University of Hawaii, East West Centre, a well known center of leftist thought. She and Barack Obama Sr. met in a Russian language class (being of mutual Marxist orientation), where she immediately began an intimate relationship with him. Although still married to Kezia in 1960, Senior may or may not have married Anna. If he did he became legally a bigamist according to US federal law. 

Obama Jr. was born on August 4, 1961. While Anna’s parents weren’t happy with this union, Barack Sr.’s father was furious. 

“He didn't want the Obama blood sullied by a white woman,” notes Obama in his Memoirs.
 

Obama Jr.’s birth certificate is not a true copy of an original, certified document, according to a detailed analysis of the image and the text. Nothing in this copy indicates that it is, in fact, a "certified copy."  A lot of evidence points to a manufactured copy.L

Obama refused to release his birth certificate as well as his passport nor other vital records. What is he hiding? 

Unless the voting public is given a real birth certificate to examine, the question of Barack's birth is still up in the air⁸.

Obama's Muslim stepfather registered him at the Fransiskus Assisi Catholic school, a Catholic school in Jakarta - perhaps in deference to Ann's Christian heritage - where Obama completed his first 3 grades, yet never studied "Catholic catechism". 

Obama then entered the Besuki Primary School, a state school he attended for 2 years. He was enrolled as Barry Soetoro, Muslim⁹. The students, both muslim and non-muslim alike, are all required to dress in traditional Muslim attire on Fridays. All Indonesian students are required to study religion at school and a young Barry Soetoro, being a Muslim, would have been required to study Islam daily in school (as The Houston Chronicle pointed out that Senator Obama's religion in the school records as a child in Indonesia was Islam).

He would have been taught to read and write Arabic, to recite his prayers properly, to read and recite from the Quran and to study the laws of Islam. 

Quote from “The Obama File”: However, Obama received additional training. As the principal from 1971 through 1989, Tine Hahiyary, remembers, Obama had studied "mengaji."

Our guy in Jakarta writes: "The actual usage of the word 'mengaji' in Indonesian and Malaysian societies means the study of learning to recite the Quran in the Arabic language rather than the native tongue. "Mengaji" is a word and a term that is accorded the highest value and status in the mindset of fundamentalist societies here in Southeast Asia. To put it quite simply, 'mengaji classes' are not something that a non practicing or so-called moderate Muslim family would ever send their child to. To put this in a Christian context, this is something above and beyond simply enrolling your child in Sunday school classes."

"The fact that Obama had attended mengaji classes is well known in Indonesia and has left many there wondering just when Obama is going to come out of the closet."

"As I've stated before, the evidence seems to quite clearly show that both Ann Dunham and her husband Lolo Soetoro Mangunharjo were in fact devout Muslims themselves [Annelore's comment: then Ann would not wear a dress that shows her legs above the knees] and they raised their son as such."EndofQuote

Barack Obama attending a “madrassa” (“religious school”) as a child first broke on Fox News last year. He regularly attended Friday prayers with his stepfather Lolo Soetoro. A former school mate pointed out the "Musholla Al-Rahman" (Al-Rahman Prayer Room) to the reporter but then went out of his way to explain that Obama wasn't really "praying" in the prayer room, he was only "playing".

Obama’s half-sister Maya Soetoro was quoted by the New York Times as saying, "My whole family was Muslim." She said that her brother had lived in Indonesia between the years of 1968-1973.
