Yes, she said this:

"When presented with a passenger carrying a large sum of money through the screening checkpoint, the TSA officer will frequently engage in dialog with the passenger to determine whether a referral to law-enforcement authorities is warranted.

The TSA officer may consider all circumstances in making the assessment, including the behavior and credibility of the passenger. Thus, a failure to be forthcoming may inform a TSA officer’s decision to call law-enforcement authorities."

What she didn't state was the law: You are NOT required to answer any questions regarding cash. If the TSA refers you to law enforcement on the basis of your refusal to answer questions unrelated to security (or, better still, respond, "None of your business"), they are committing a violation of both the 1st and 5th Amendment. However, this "referral" will be interesting as TSA has absolutely no right to detain anyone, and no right to seize your money.
