Sam Clovis

Updated 12:30 p.m. Nov. 2 — Sam Clovis, who ran President Donald Trump's campaign in Iowa, has withdrawn his nomination to the U.S. Department of Agriculture's chief scientist position. Clovis was linked this week to the federal investigation of Russian interference in the 2016 election.

Clovis sent Trump a letter, dated Nov. 1, that says the political climate "has made it impossible for me to receive balanced and fair consideration for this position" during his Nov. 9 Senate confirmation hearing.

As President Donald Trump continues to fill political appointments, his nomination for the top science job at the U.S. Department of Agriculture is raising unique concerns.

Trump has chosen Iowan Sam Clovis to be undersecretary of agriculture for research, education and economics. Clovis served as a fighter pilot in the Air Force, has a doctorate in public administration, and taught economics at Morningside College in Sioux City.

Sioux City is also where he gained a following as a conservative talk show host.
