U.S. Congressman, U.S. Senator. He was an American politician, who started his political career as a member of the Democratic-Republican Party, who served in the Delaware General Assembly. Born into a well-respected family, his uncle, also named Caesar Rodney, was one of the signers of the Declaration of Independence. After graduating from the University Pennsylvania in 1789, he studied law and was admitted to the bar in 1793 before beginning a law practice. He served as the United States Attorney General from 1807 to 1811 under Presidents Jefferson and Madison. He was elected as the US Representative from Delaware, serving from 1803 to 1805 and from 1821 to 1822 before being a US Senator from Delaware from 1822 to 1823, when he resigned. Twice, while in Congress, he led impeachment hearings against federal judges: John Pickering, who was removed, and United States Supreme Court Justice Samuel Chase, who was not removed after an appeal. He was appointed US Minister Plenipotentiary to Argentina in 1823 and served until his death in Buenos Aires in 1824. After the Argentine government gave Rodney a hero's funeral his remains were initially interred in the Victoria District British Cemetery. Sources from the United States House of Representative Archives state that in 1923, his remains were moved to the British Cemetery in Charcarita District at Buenos Aires. When attempts were made in 1999 to repatriate his remains to the family cemetery in Delaware, his remains could not be located. Argentine authorities and the US State Department came to the conclusion that his remains were buried in what is now in the 21st century a common unmarked grave in an unknown Buenos Aires cemetery. In 1832 marble monument was placed at St John's Cathedral by the Argentinean government, which would be a cenotaph as his remains are elsewhere.
