• Tributes say Enzi worked for bipartisan co-operation
• Police say no evidence anyone else involved in accident

Mike Enzi, a retired Wyoming Republican senator known as a consensus-builder in an increasingly polarized Washington, has died. He was 77.

Enzi died on Monday surrounded by family and friends, former spokesman Max D'Onofrio said. Enzi had been hospitalized with a broken neck and ribs after a bicycle accident near Gillette on Friday. He was stabilized before being flown to a hospital in Colorado but remained unconscious, D'Onofrio said.
