In a move that could provide Hillary Clinton with major organizational support in the key caucus state of Iowa, Former Iowa Governor and brief Presidential candidate Tom Vilsack will be endorsing her at an event in Des Moines this Monday, the Associated Press reports, quoting unnamed officials.

"Vilsack and his wife, Christie, planned to make the endorsement on Monday when the New York senator will be in the state, the officials said. They spoke on condition of anonymity because of the planned formal statement next week," the AP says.

Tom Vilsack's backing comes with an added bonus: His wife, Christie Vilsack, who has a proven track record as a king-maker in the state. In 2004, her support of John Kerry's trailing primary campaign helped propel him to a come-from-behind victory in the Iowa caucus.
