Caleb Jefferson McNulty (December, 1816 – July 12, 1846) was an American lawyer, newspaper editor and politician. Active in the Democratic Party, he became Clerk of the U.S. House of Representatives; while serving in this post he was alleged to have embezzled congressional funds; some charges were subsequently dismissed, and he was acquitted of the others. John Quincy Adams, then serving as a Whig member of the House, referred to the charges as a "memorable development of Democratic defalcation."[1]
