Newly released video shows 9/11 hijackers with alleged Saudi intelligence operative

While President Biden signed an executive order last fall to declassify 9/11 evidence, the families of some 9/11 victims say they had to go through the British courts to get records and videos seized two decades ago from an alleged Saudi government operative that have never been public until now.

"Why did it take 20 years for this information to see the light of day?" Brett Eagleson told CBS News senior investigative correspondent Catherine Herridge.

He is leading a group of families fighting for the documents. He was 15 years old when his father, Bruce, was killed in the World Trade Center South Tower, and 20 years later, he wants his children to know what he calls "the secret of 9/11" and who was behind the plot to kill their grandfather. 

"Will the Justice Department now explain to the families and to America why they did not pursue charges against (Saudi national Omar) al-Bayoumi? And most astonishingly, why did this information come from the U.K. government and not our own FBI?"
