Sen. Michael Bennet (D-Colo.) is leading a letter signed by 14 other senators urging Agriculture Secretary Tom Vilsack to help Western states survive what they are calling a “22-year mega-drought” that is threatening farms and ranches across the West.  “The American West is in crisis. Across the major basins of the American West … farm and ranch families hang in the balance as they grapple with a 22-year mega-drought,” they warned.
