There is, but like all of the other wikileaks 'scandals' there's nothing there when you actually look at the context. She said it as a joke, got the room to laugh, and moved on. Read the sources, there is really nothing to these leaks.

edit2: Notice the colorful language: she "openly inquired" instead of "joked". The laughter "died" when she "kept talking in a terse manner". It's all doublespeak.
