I am thinking the same thing. She didn't know anything about any money delivery (because nothing was scheduled anyway, money was ransom money and not a scheduled delivery). She found out from the press because they were asking her if she knew about the money.
She then called the assistant and he confirmed he delivered the money. She then started telling reporters she knew about the money. Then she also told reporters she didn't know about the money (which she didn't originally).
But anything that comes from her, you have to guess what she means.
This would mean she (or someone else) would have had to talk to JW after the day before the murders.
