U.S. Agriculture Secretary Tom Vilsack plans to return to Des Moines when President Barack Obama leaves office, The Des Moines Register reported. “We’ve had a house in Des Moines for a while, and we have three grandchildren, so it’s not rocket science to figure out we’re going back to Des Moines,” he told reporters following a speech before the Organic Trade Association in Washington. “I don’t know what we are going to do or when we are going to go back, but that’s home.” Vilsack, who was born in Pittsburgh, has lived most of his life in Iowa and is a legal resident of the state.
