Today we remember the tragedy of September 11, 2001 and reflect on the events and heroic acts that changed our nation forever. We honor the memory of those who were lost and pay tribute to the brave officers and fire fighters who gave their lives to protect their fellow Americans that day.

Though seven years have passed, we still remember those sacrifices that truly embody the home of the brave. Today is also a day to honor our men and women in uniform who fight to protect us and ensure that freedom endures.

The Pentagon Memorial will be open to the public from 7 p.m. to 9 p.m. EDT this evening. The opening will include a musical tribute featuring the Navy Band and the Sea Chanters Chorus, the official chorus of the U.S. Navy. This will be the first opportunity for the general public to view the memorial in remembrance of the lives lost on Sept. 11 at the Pentagon and on American Airlines Flight 77.

Please keep our men and women in uniform and their families in your thoughts and prayers, and let us never forget those who lost their lives on this infamous day seven years ago.
