SHELTON, Wash. — Rep. Mike Simpson was the only member of the Northwest congressional delegation to attend the first day of the Salmon and Orca Summit here, where all involved expressed the need for urgent action to save the two species intertwined in the culture and natural history of the Pacific Northwest.

The Republican from Idaho has largely been alone since he introduced his $33 billion salmon and dams concept back in February but has won the support of tribes throughout the Pacific Northwest and beyond.
