Obama reflects on 20th anniversary
Former President Barack Obama released a statement Saturday morning reflecting on the 20th anniversary of the Sept. 11 attacks.
He urged all Americans to remember the courage and selflessness of those lost in the attacks.
"We reaffirm our commitment to keep a sacred trust with their families — including the children who lost parents, and who have demonstrated such extraordinary resilience. But this anniversary is also about reflecting on what we’ve learned in the 20 years since that awful morning," Obama wrote.
"That list of lessons is long and growing. But one thing that became clear on 9/11 – and has been clear ever since – is that America has always been home to heroes who run towards danger in order to do what is right."
In his statement the former president pointed to examples of heroic actions from the last two decades, such as the service members, first responders and medical personnel.
"They represent what is best in America, and what can and should bring us together," Obama said. "9/11 reminded us how so many Americans give of themselves in extraordinary ways – not just in moments of great crisis, but every single day. Let’s never forget that, and let’s never take them for granted."
