In less than 10 days, the collective heart of our nation will take pause in somber reflection on the 20th anniversary of the 9/11 terrorist attacks. We will join in a National Day of Service to honor the memories of those who paid the ultimate sacrifice. We will also remember thousands of service members who were killed fighting the Global War on Terror, as well as thousands more firefighters, EMTs and police officers who died as a result of their exposure to unthinkable conditions that fateful day.
