John Middleton Clayton

John Middleton Clayton was an American lawyer and politician from Delaware. He was a member of the Whig Party who served in the Delaware General Assembly, and as U.S. Senator from Delaware and U.S. Secretary of State.

Delaware politics :

Clayton was elected to the Delaware House of Representatives for the 1824 session and was appointed the Delaware Secretary of State from December 1826 to October 1828. Conservative in background and outlook, Clayton quickly became a leader of the Adams faction which later developed into the Delaware Whig Party. During this time he was also the driving force in the convention that produced the Delaware Constitution of 1831.

National politics:

In 1829 Clayton was elected to the United States Senate as its youngest member. Six years later he declined re-election, but the General Assembly elected him anyway, only to have him resign. He served from March 4, 1829, until December 29, 1836. He distinguished himself in the Senate by a speech during the debate on the Foote resolution, which, though merely relating to the survey of the public lands, introduced into the discussion the whole question of nullification. Clayton favored the extension of the charter for the Second Bank of the United States and his investigation of the Post Office Department led to its reorganization. At various times he served on the Military Affairs, Militia, District of Columbia and Post Office Committees, but his most important position was the Chairmanship of the Judiciary Committee in the 23rd and 24th Congress.[citation needed]

After returning to Delaware from his first term in the United States Senate, Clayton was appointed Chief Justice of the Delaware Superior Court, replacing his cousin Thomas Clayton, who had been elected to the vacant U.S. Senate seat. He served in this position from January 16, 1837 until September 19, 1839, when he resigned to support the presidential candidacy of William Henry Harrison.

Clayton was once again elected to the United States Senate in 1845, where he opposed the annexation of Texas and the Mexican–American War but advocated the active prosecution of the latter once it was begun. His tenure was only from March 4, 1845, until February 23, 1849, as he resigned to become U.S. Secretary of State.

On March 8, 1849, Clayton became U.S. Secretary of State in the Whig administration of Zachary Taylor. His most notable accomplishment was the negotiation of the Clayton–Bulwer Treaty of 1850 with the British minister, Sir Henry Bulwer-Lytton. This treaty guaranteed the neutrality and encouragement of lines of travel across the isthmus at Panama, and laid the groundwork for America's eventual building of the Panama Canal. His tenure was brief, however, ending on July 22, 1850, soon after President Taylor's death.

As secretary of state, Clayton was intensely nationalistic and an ardent advocate of commercial expansion but his strict interpretation of international law created crises with Spain, Portugal, and France.[citation needed]

Clayton was again elected to the United States Senate one last time in 1853 and served from March 4, 1853, until his death on November 9, 1856. He opposed the Kansas-Nebraska Act. One of his most noted speeches delivered in the Senate was that made June 15, 1854 against the message of U.S. President Franklin Pierce, vetoing the Bill for the Benefit of the Indigent Insane, which would have ceded public lands for an insane asylum.
