Ex-FBI agent who worked on secret 9/11 case says hijackers had a U.S-based support network

Nearly 20 years after the 9/11 terror attacks, some victims' families are still pressing the U.S. government for more information on possible ties between Saudi leaders and the attackers. CBS News spoke exclusively with a retired FBI agent who was part of a still-secret investigation into the hijackers' network inside the U.S. Catherine Herridge reports.

Imagine knowing this for almost 20 years and being called crazy by everyone including the government

[didyouknowamazingfacts]

It's just crazy how we just attacked 2 countries that had no association with 911.

[gardensofthegods]

Something's seriously wrong when they're not allowed to tell the truth .
These two men definitely need protection .

[IndependentMind]

It makes my blood boil to think that our own government was involved. 🤬🤬

[NeutronRob]

Only took about 21 years and 6 months to tell the truth. It was clearly evident they had domestic associates who knew what they were up to and gave aid.

[lrboipi]

We know what happened and we know the truth will never come out. Such a shame

When something is being kept a secret/files hidden away means something is being covered up.

My brother was murdered on08/11/01 in the WTC. My family lost a brother who was also an uncle. I have yet to receive any of his remains and a thorough explanation of how this event event happened. I truly believe the murderer s had an excellent support system with our own country. They were well trained to achieve what they accomplished m. I miss my brother everyday…

[rodrigogutierrez]

Let me get this right.. we pay taxes yet we can't look at those documents ? All that information is payed for by our tax dollars

Look at JFK case
Files still not released how many years later

I hope these former FBI agents stay safe 🙏🙏

[NahNah]

This was a very calculated attack. It took a lot of planning strategy! I never believed that it just happened! RIP to all of the victims!😔

[alonzobean]

The problem, as always is that the FBI will not speak to an ongoing investigation. Therefore the investigation will never end.

[richiesspeedshop]

They had a support based system. It's called the U.S. Governement.

May everyone who passed that day Rest In Peace 🙏🙏🙏🙏

When Gonzalez, the FBI agent says “11 guys committed 3, 000 mass murders” when you take a step back and forget what we’ve been fed for 20 plus years it does sound preposterous that they were some rogue group who acted alone.

[johndunn]

Twenty years later it's hard even remembering not having the "patriot act" making it legal to commit random search and seizure against presumed innocent citizens.

The biggest red flag was when they were at flight school the terrorist did not want to learn how to land. How does that not raise suspicion?

[carolegable-hawrylik]

To think that this could have been possibly prevented, is enough to infuriate any American ! Too many lives were lost during, and after that horrific criminal event. Too many lives were torn apart, and any other information regarding this crime must be revealed ! - Jen Gable (Justeson)

[keziajulian]

One thing I’ve learned….never trust the US FBI nor the US Govt.
