He was elected to the U.S. Senate for the term commencing March 4, 1851, and served from May 12, 1852, to March 3, 1857, having that year declined to be a candidate for reelection.
James Buchanan appointed him U.S. Secretary of the Navy in his Cabinet in 1857 and he held that post until 1861 and the arrival of the Abraham Lincoln administration. After 1861 he returned to the law, and died in Hartford in 1869.
