Senator Amy Klobuchar (D-Minn.) was one champion of the pizza rollback. Minnesota is home to Schwan Food Co, a private company with nearly $3 billion in sales and 70 percent of the school frozen pizza market. Klobuchar, who is running for re-election this year, wrote a letter last June to the Department of Agriculture. One sentence in it was identical to that in a Schwan official’s later testimony before a Senate committee. The similarity was first reported by Minnesota Public Radio.

Both documents contained this statement: “By changing the crediting, many tomato-based sauces and salsa-type applications would no longer be factored into the weekly requirements for vegetables.”

Klobuchar’s spokesman, Linden Zakula, said he could not explain how the same language was used in the senator’s letter because the aide who drafted it had left. He said Schwan was among many constituents to contact the office. Schwan declined to comment.
