WATCH: Moments of silence were held at the White House and the Capitol Wednesday morning to remember those killed in the terrorist attacks on Sept.11, 2001.
The September 11 memorial is one of the most moving tributes I have ever seen. Simple and profound. #Sept11
My love 4 the USA is constant but on #Sept11 I wake up w/ such a sense of pride..Ill never 4get & always thankful 2 those serving our nation
With so many #Sept11 secrets, we cannot move forward as a nation and end terrorism.
As we remember that tragic morning ten years ago today, let us work together for better understanding and reconciliation. #Sept11
We stand w/ victims & survivors of the #Sept11 crime against humanity. They have the right to justice & reparation.
I call for a new investigation into the #Sept11 attacks to address information gaps about that horrific day.
