Maybe some one could simply ask her?
She'd lie. If she provided false information to begin with, there's no reason to believe she'd tell the truth now.
Grandma gave one tightly controlled interview to David Mendell in 2004 after Obama’s speech at the Dem Convention. She has severe osteoporosis and had a corneal transplant this past summer. She did want to do an interview with “The Honolulu Advertiser” when they did the story about her but according to Soetoro Ng decided it wouldn’t be fair considering all the media requests which have been made. When media are lucky enough to contact her on the phone she informs them she doesn’t do interviews as she is unwell. One enterprising reporter was arrested while trying to climb a pole on the outside of the apartment building where grandma lives on the 10th floor. At one time Maya used to take her out every evening to watch the sunset but I don’t know if she still does.
