Levin then engages in a mini "history" lesson:
The censure of a president was employed once in our history. In 1834, The Whig-controlled Senate voted to censure President Andrew Jackson, a Democrat, for vetoing an extension of the charter of the Bank of the United States. While legally meaningless, Jackson was deeply offended by it. And when his party regained control of the Senate in 1836, he insisted that the record be expunged -- and it was. The primary proponent of Jackson's censure is largely unknown to history, as Feingold will be.(emphasis added)
It took about five seconds to find out how little Levin knows. The "unknown to history" proponent of censure was Henry Clay, one of the more prominent Americans from the first half of the 19th century.
