Obama has told his share of lies.
One is that he was poor in Hawaii.
His stepfather, Lolo Soetaro, a Shell Oil executive for Indonesia and later liason between the Indonesian government oil company and Shell, was extremely well-to-do, and was well able to pay a large settlement to his ex-wife when they divorced.
This paid Barack Obama's fees at Punahou in the 1970s, from age 10, when he left Indonesia for schooling, entering the fifth grade, to graduation at age 18 in 1979; Punahou is one of the most exclusive and expensive private schools (fees now $15725/year) anywhere.
Obama says he had a scholarship, which is a lie. Scholarships are available at Punahou only to descendants of the old missionary families and to those with Hawaiian blood.
Incidentally, the settlement also paid for his mother's expedition through central Asia, and her work on her doctoral dissertation on Indonesian workers.

Obama has frequently exaggerated his roll in legislation in the Senate; see a current thread, American Government Owners' Manual, and its link to "Barack's "Obama-isms," for reference to some of his questionable statements.
