Furthermore, when the leaker was revealed to be 21-year-old Jack Teixeira, an Airman First Class in the Massachusetts Air National Guard, the American public had even more questions. How did a young, low-ranking soldier have access to classified government information, and why did he expose U.S. intelligence information to potential adversaries when he is actively defending the country?
