Jackson Interrupts Robert Hayne's Toast To Openly Challenge John C. Calhoun

Particularly notable was an incident at the April 13, 1830 Jefferson Day dinner, involving after-dinner toasts.

Robert Hayne began by toasting to "The Union of the States, and the Sovereignty of the States." Jackson then rose, and in a booming voice added "Our federal Union: It must be preserved!" – a clear challenge to Calhoun. Calhoun clarified his position by responding "The Union: Next to our Liberty, the most dear!"

The next year, Calhoun and Jackson broke apart politically from one another. Around this time, the Petticoat Affair caused further resignations from Jackson's cabinet, leading to its reorganization as the "Kitchen Cabinet." Martin Van Buren, despite resigning as Secretary of State, played a leading role in the new unofficial cabinet. At the first Democratic National Convention, privately engineered by members of the Kitchen Cabinet, Van Buren replaced Calhoun as Jackson's running mate. In December 1832, Calhoun resigned as Vice President to become a U.S. Senator for South Carolina.

Our federal Union: It must be preserved!”
