CHICAGO (CNN) - President-elect Barack Obama will name former Iowa Gov. Tom Vilsack as his secretary of Agriculture at a news conference scheduled for Wednesday, according to an Obama transition aide and a separate Democratic source.
Vilsack was a high profile supporter of Hillary Clinton during the presidential primaries after he briefly sought the Democratic presidential nomination.
Obama and Vilsack were rivals for the Democratic nomination for just under two weeks.
