This was in an email, so we have no way of knowing if she said this with a straight face or not.

In answer to a detailed series of questions from the Guardian, a Fiorina spokeswoman said in an emailed statement: “We were happy that these children chose to come to Carly’s event with their adult supervisor.”

In addition to the event itself there is a picture clearly showing the kid's faces. You just cannot show kid's faces like that without a written release from the parents - which they obviously did not get.

Seems to me that "adult supervisor" has some 'splainin to do also.
