Found a site with a written transcription of the Manning video:

Some excerpts:

Obama was recruited in 1980 by the CIA while a student at Occidental College in Los Angeles, California. The CIA needed Muslims who were fluent in Farsi and other Islamic customs and understandings....

He excelled at Harvard, became the Editor of the Law Review. Where upon his graduation he could have become a Supreme Court clerk or a multi-million dollar salary would have been offered to him at America's best law firms, except for one thing...he did not have a legitimate background as a US Citizen or as a student from Occidental or Columbia. A diligent investigation by a personnel agency of a major law firm would have revealed he was not a US citizen. And how could a "C" student go from Occidental College to America's fifth most difficult school to enter, into Columbia University, and then from there three years later enter into the world's most difficult lawschool, Harvard?...

So what does a former CIA operative do when they cannot pass a personnel test? Obama becomes a "Community Organizer" on the South side of Chicago, where no background check is needed. His marriage to Michelle Robinson, a lawyer and connected Chicago politician, although a convenient marriage, now gives him citizenship and the beginning of a solid background. He takes a job at the same law firm where Michelle becomes his trainer and supervisor, a law firm that is heavily influenced by small time criminal, Tony Rezko. Michelle Robinson controls the personnel records, and his hiring takes place without a hitch....

And so on. There's another video on the page too, about witnesses Manning plans to call.
