Republican Secretary of Agriculture Bill Northey had served in the position since 2007. Northey was considering running for Iowa governor, but after Governor Terry Branstad was nominated to be Ambassador to China, he announced he would not run.[12][13] Northey had not ruled out running for reelection in 2018, but said he would be willing to serve as lieutenant governor instead if asked.[14] In 2018, he was nominated by President Donald Trump to be Under Secretary of Agriculture for Farm and Foreign Agricultural Services, and subsequently ruled out reelection. The office was then held by Mike Naig, serving in an acting capacity.
