Where Has She Been

If all of President Obama's father's children write a book about their lives never really knowing their brother. It could  take a very long time. The president has five siblings that we already know about, and at least two where paternty isn't certain. My wife doesn't agree with me. But I think the president and his sister look alike.  Why is she in the news all of a sudden? Where has she been all this time?
