New Castle, Delaware, for the next three years. Rodney married Susan Hunn, the daughter of Captain John Hunn, and their home was "Cool Springs", located in Wilmington.
Professional and political career
Rodney served six terms as State Representative, from the 1797 session through the 1802 session. There he became one of the leaders of the Jeffersonian party, now known as the Democratic-Republican Party. Encouraged by Jefferson to compete for the U.S. House against the staunch
Federalist James A. Bayard, Rodney ran and won a lively campaign by fifteen votes. While in the U.S. House, he was a member of the
Committee on Ways and Means, and established a national reputation as one of the
impeachment managers appointed in January 1804 to prepare and prosecute the
articles of impeachment in the

After serving one term in the U.S. House from March 4, 1803, until March 3, 1805, he was defeated for reelection in 1804 by Bayard, by nearly as close a vote. The two men, always vigorous political opponents, remained good friends throughout their tumultuous political careers.
While Rodney spent most of his legal career in public service, he took on at least one notable case as a private advocate during the year before his appointment as Attorney General. In 1806, he made an appearance before the Mayor's Court of Philadelphia to defend the
Philadelphia Cordwainers against a common law charge of conspiracy. The conspiracy charge was instituted by retail shoe merchants, based on attempts by the journeyman shoe and boot makers, to organize for the purpose of setting their wages and hours. Rodney was unsuccessful in attaining an acquittal for the workers.

Later political activity
Rodney returned to politics, serving in the
Delaware State Senate for three sessions from 1815 through 1817. In 1820 he was again elected to the U.S. House, serving from March 4, 1821, until January 24, 1822, when he resigned upon being elected to the U.S. Senate. He served there only a year as well, resigning January 29, 1823, to accept a diplomatic appointment. During that brief year Rodney was Delaware's only Democratic-Republican U.S. Senator ever.

n republics should be recognized. He strongly advocated such recognition and, with Graham, published his findings in 1819 as ''Reports on the Present State of the United Provinces of South America.'' This report is thought to have contributed much to the thinking behind the policy that eventually became expressed as the
Monroe Doctrine. It also resulted in Rodney's 1823 appointment as United States
