Pres. Obama presides over dedication ceremony of new 9/11 Memorial Museum
A somber ceremony took place in lower Manhattan today as President Obama joined survivors, families of victims, and first responders for a dedication of the 9/11 memorial museum.
The museum is built underneath the footprint of the fallen Twin Towers.
Organizers say that the exhibits honor nearly 3,000 people who died on Sept. 11 as well as in the attack on the World Trade Center in 1993.
