Christina Taylor Green was born shortly after the Sept. 11 terrorist attacks in 2001. Her father, John Green, is a scout for the Los Angeles Dodgers. Earlier, he was a scout with the Baltimore Orioles and had a family farm in Conowingo, Md.
Christina's mother, Roxanna Green, said Christina was always aware she was born on 9/11 and was very patriotic.
A year after her birth, Christina-Taylor was among the children featured in the book "Faces of Hope: Babies Born on 9/11." It chronicled one baby from each state born on the day terrorists killed almost 3,000 people.
The girl's uncle said a neighbor was going to the Giffords event and invited Christina because she had just been elected to student council and was interested in government, the Arizona Republic reported.
