Although identified in various sources as a photograph of Obama and the young man with copious hair and glssses was taken at Occidental, it might possibly be from Punahou. As I wrote, I cannot recall the name of the student from Hawaii who it was reported, also enrolled at Occidental at the same time as Obama.
That all the images of the young man with glasses are Thomas Hamilton Krieger isn’t in doubt.
What is in serious doubt is that Michelle was a young coloured man in the company of Obama and Thomas - be it at Punahou or Occidental.
