President Donald Trump and First Lady Melania Trump held a moment of silence Wednesday in commemoration of the lives lost in the 9/11 terror attacks.
The president and first lady exited the White House and stood briefly on the East Lawn as a bell chimed three times.
Bowing their heads, and clasping their hands, they remained silent for a moment.
The pause of silence began at 8:46 a.m. EDT, the time the first plane, American Airlines Flight 11, struck the North Tower of the World Trade Center on September 11, 2001.
White House staff and family members of those lost in the attacks joined them.
Following the moment of silence, the military played taps before the president and first lady returned to the White House.
