Los Angeles Times: Robert Carlyle Byrd, the West Virginia Democrat who was often called this generation's conscience of the Senate for his devotion to the system of constitutional checks and balances and the prerogatives of power, died Monday. He was 92. Byrd, who served longer than any member of Congress in U.S. history and cast more congressional votes than anyone since taking office in January 1959, died at about 3 a.m. at Inova Hospital in Fairfax, Va., a spokesman for the family said.
