INDIANAPOLIS (AP) — Indiana's departing U.S. Sen. Richard is leaving the Senate with one last act of compromise in support of Congress' "fiscal cliff" deal.
The Republican will leave the Senate on Thursday after having cast 13,067 votes over nearly four decades in Washington. U.S. Rep. Joe Donnelly is being sworn in as Indiana's newest senator after defeating state Treasurer Richard Mourdock in November's election.
Lugar's final vote caps decades of work across party lines. That compromise helped lead to his ouster in last year's Republican primary by Mourdock.
Lugar's service places him 10th on the list of total votes cast in a Senate career. West Virginia's late Sen. Robert Byrd tops that list with 18,689 votes cast over 50 years in the chamber.
