UPDATE: 11-13 9:35 AM: Did Hillary answer a second planted question at the event? See foot.

What did Hillary Clinton know about the planted question in Iowa and when did she know it?

The Clinton campaign and apparently Clinton herself are denying she had any idea she was calling on a plant. But according to information in the New York Times, Clinton campaign aides had in fact prompted her to call on the plant.

At 10:51 AM ET this morning, MSNBC anchor Tamron Hall interviewed Hillary campaign co-chair Tom Vilsack, the former Dem governor of Iowa.

TAMRON HALL: Senator Clinton herself said she knew nothing about this and promised it would not happen again . . .

TOM VILSACK: Obviously Hillary Clinton does not condone the planting of questions; she did not know that this young person had been given that question.

Vilsack elaborated on his answer later in the interview.
