President-elect Barack Obama has nominated former two-term Iowa governor Tom Vilsack, a strong proponent of biofuels, to be the 30th secretary of agriculture.

At the same time, Obama nominated Sen. Ken Salazar, D-Colo., and a farmer and rancher in Colorado's San Luis Valley, to be secretary of interior. He is an attorney with an expertise in water issues.

In a U.S. Department of Agricultur press release, current ag secretary Ed Schafer praised Obama's choice of Vilsack.


"USDA plays an integral role in supporting our agricultural economy and working on behalf of America's farmers and ranchers. I am confident that Tom Vilsack's background and experience will help him continue the progress we have made here."
