John C. Calhoun resigns, becoming the first…
December 1832 CE
As tensions over nullification escalated, South Carolina Senator Robert Y. Hayne was considered less capable than Calhoun to represent South Carolina in the Senate debates, so in late 1832 Hayne resigned to become governor.
Calhoun now resigns as vice president to become a senator, with a voice in the debates.
Martin Van Buren had already been elected as Jackson's new vice president, meaning that Calhoun has less than three months left on his term anyway.
