A bipartisan group of senators from western states are asking the Environmental Protection Agency inspector general to investigate all aspects of a recent spill in Colorado. The senators are asking the inspector general to probe everything from the work EPA contractors were doing in the Gold King Mine before the August 5th spill to the safeguards the agency put in place to prevent other spills in the future. The senators, led by Colorado republican Cory Gardner, sent the letter on Wednesday. EPA’s inspector general announced an investigation into the spill earlier in the week.

A weakened farm economy and energy industry has led to Deere & Company to reduce is fiscal 2015 profit forecast. The move is in response to lower grain prices and lower sales of construction machinery. Deere now sees total equipment sales falling 21 percent for the year, worse than an earlier projection for a 19 percent decline. Net income for the year through October will be about $1.8 billion, the Moline, Illinois-based company said Friday in a statement. That’s less than the $1.9 billion that Deere forecast in May.
