President Barack Obama, former New York mayor Mike Bloomberg, survivors and relatives of those who died on Sept. 11, 2001, delivered moving remarks at a dedication ceremony at New York City's National September 11 Memorial & Museum on Thursday.
The museum opened its doors for those most directly affected by the events of that day, nearly one week before opening next Wednesday to the general public.
"Here at this memorial, this museum, we come together. We stand in the footprints of two mighty towers,” President Obama said, staring in front of the famed "slurry wall” that held off the Hudson River in the days after the attack.
"We tell their story so that generations yet unborn will never forget."
