Senator Robert Byrd of West Virginia, the longest-serving senator in American history, died Monday at the age of 92, a spokesman for the family said.
Byrd, a Democrat who served in the U.S. Senate since 1959, had been plagued by health problems in recent years and was confined to a wheelchair. He had skipped several votes in Congress in the past months.
Jesse Jacobs, a family spokesman, said Byrd died peacefully at about 3 a.m. at Inova Hospital in Fairfax, Va.
He was the oldest member of the 111th Congress.
The passing of Sen. Byrd will not affect the balance of power in the Senate. West Virginia Governor Joe Manchin, a Democrat, will appoint a replacement senator to serve out the remainder of Byrd's term which ends in 2012.
Byrd held a number of leadership roles during his tenure in the Senate, including conference secretary, majority whip and majority leader -- twice.
Prior to his death, Byrd worked as the president pro tempore -- the second highest ranking official in the Senate and the highest ranking senator in the majority party, putting Byrd third in line to the presidency.
He also served as the senior member of the Senate Appropriations Committee, and the chairman of the Senate Appropriations Subcommittee on Homeland Security. Other committees on which Byrd served were the Senate Budget, Armed Services and Rules and Administration Committees.
Byrd, who never lost an election, cast more than 18,540 roll call votes -- more than any other senator in U.S. history. He had a 98 percent attendance record in his more than five decades of service in the Senate, according to his Web site.

It'll be amusing to watch our "First Black President" eulogize a former Klansman.
