His death occurred eight days before the 2002 midterm elections, leading to a widely observed appointment and special election cycle in Minnesota.
Senator Fritz Hollings (D–SC)
Died April 6, 2019, in Charleston, South Carolina. Retired from the Senate effective January 3, 2005 after 38 years of service (1967–2005). Although he left office years earlier, his death in 2019 brought renewed attention to his long tenure and bipartisan negotiation style.
Senator Daniel Inouye (D–HI)
