FOX News Rundown EXTRA: The 20th Anniversary of September 11th

Today is the 20th anniversary of the 9/11 terror attacks. Nineteen Al-Qaeda terrorists hijacked four airplanes and carried out suicide attacks in the U.S. that day. Two of the planes were flown into the Twin Towers in New York City, a third plane hit the Pentagon in Washington, D.C., and the fourth plane crashed in a field in Shanksville, Pennsylvania. Nearly 3,000 people were killed, changing so many Americans lives forever.

Earlier this week, host Jessica Rosenthal spoke with Chairman and CEO of the Tunnel 2 Towers foundation, Frank Siller. Siller lost his firefighter brother, Stephen Siller on September 11th. This year to honor his late brother and the victims who died, Frank Siller embarked on his NEVER FORGET walk. The over 500- mile journey started at the Pentagon in Washington D.C. to Shanksville, PA and ended on Saturday at Ground Zero in New York, reunited with his family.

The conversation was too long and we could not include the whole interview with Mr. Siller. On today's FOX News Rundown EXTRA, with less than 10-miles to go on his walk when we spoke to him, the Tunnel 2 Towers Chairman and CEO told the Rundown what was going through his mind throughout his trek from Washington back to New York and why he felt it was important to do this walk. He shares his story about his brother and what happened to him on 9/11, he explains why it's important to share the story of 9/11 with the younger generation and the importance of never forgetting what happened on that day. He weighs in on the recent events on Afghanistan and if it impacts the 20th anniversary. Plus, he talks about his foundation Tunnel to Towers how the foundation helps families who have lost loved ones who are first responders or Gold Star families and why it is important to help those who serve to keep America safe.
