Wonder if she has an Irish Passport?
I read that her father emigrated from Ireland and her mother is a first generation Irish-American.
I have no way of knowing this, but I had friends whose parents and/or grandparents immigrated from Ireland and they were eligible to get an Irish passport. Most of them did it for two reasons: First off, there were places that they could go on an Irish passport that they couldn't on an American one, such as Cuba or Vietnam. The second reason was that it doesn't hurt to have another passport... just in case you find yourself in a situation where they don't like Americans and have to RUN.
