Idaho's two U.S. senators and two U.S. representatives are asking the U.S. Department of Agriculture to buy potatoes from Idaho growers in a move to help ease difficult economic times for some farmers. The potatoes could go to public schools or federal nutrition programs under the USDA's Section 32 program.
Sen. Mike Crapo posted a letter to the USDA on his website (pdf), which includes signatures by Sen. Jim Risch and Reps. Walt Minnick and Mike Simpson. Crapo and Minnick posted news releases about the letter on their government websites.
An excerpt of the letter is below:

Potato growers are struggling right now with their returns, which are quite low. Without action, the combination of a high supply and low prices will drive many growers in the State of Idaho and throughout the country to go out of business. In today’s financial market, trying to get financing for next year’s crops could be quite difficult when producers present the returns for this year’s crop.
