Reuters: The U.S. Agriculture Department said today that it had pulled all staff from an annual crop tour after an employee was threatened, and three sources said the threat came over the phone from an angry farmer. Farmers have complained this month that a government crop report did not reflect damage from historic flooding this spring. They are also frustrated over unsold crops due to the trade war with China, falling farm income and tighter credit conditions. The police chief in Spencer, Iowa, declined to say whether police would be at a tour meeting scheduled to take place in the city tonight.
