12.28.1832: Calhoun resigns as Old Hickory’s Veep. Quotes John Yoo:
By 1831, the break with Calhoun became complete when Jackson obtained documents showing that Calhoun had attacked him during the invasion of Florida. In a letter to Calhoun accusing him of “endeavoring to destroy” his reputation, Jackson wrote “in the language of Caesar, Et tu Brute,” and declared that “[n]o further communication” between the two would be necessary.
Sounds like 24 or something.
