Waggaman was elected as an anti-Jacksonian to the U.S. Senate to fill the vacancy caused by the resignation of Edward Livingston and served from November 15, 1831, to March 4, 1835. He resumed the practice of law in New Orleans and again engaged in sugar cane planting. He participated as a principal in a duel with the former mayor of New Orleans, Denis Prieur, a political adversary, and received injuries from which he died in New Orleans in 1843; interment was in Girod Street Cemetery.
In 1840, Waggaman's daughter Christine eloped with a young Canadian lawyer, John Sandfield Macdonald, who made regular trips to Washington on behalf of the government of Upper Canada as Queen's messenger. She joined Macdonald in Upper Canada. He would go on to be joint Premier of the Province of Canada and the first Premier of Ontario.[1]
