What are Sibel's Main Claims?

Sibel makes 2 specific related claims
a) Sibel claims that she has information which proves that senior officials knew that there were plans to attack America months before 9/11.

Specifically:
"There was general information about the time-frame, about methods to be used but not specifically about how they would be used and about people being in place and who was ordering these sorts of terror attacks. There were other cities that were mentioned. Major cities with skyscrapers."
and
"President Bush said they had no specific information about 11 September and that is accurate but only because he said 11 September," she said. There was, however, general information about the use of airplanes and that an attack was just months away."
b) Sibel claims that she has evidence of a global multi-billion dollar smuggling/dealing network of weapons and drug which is hidden in plain view. Of course, there is also the requisite money-laundering infrastructure. She claims that the network comprises senior american government officials, terrorists, and 'unsavoury regimes.'

and they merge, giving us:

“drug trafficking, money laundering, foreign names and American names directly involved in the financing of the 9-11 attacks on WTC (World Trade Center) and the Pentagon.”
