<P> Calhoun also opposed President Adams' plan to send a delegation to observe a meeting of South and Central American leaders in Panama, believing that the United States should stay out of foreign affairs . Calhoun became disillusioned with Adams' high tariff policies and increased centralization of government through a network of "internal improvements", which he now saw as a threat to the rights of the states . Calhoun wrote to Jackson on June 4, 1826, informing him that he would support Jackson's second campaign for the presidency in 1828 . The two were never particularly close friends . Calhoun never fully trusted Jackson, a frontiersman and popular war hero, but hoped that his election would bring some reprieve from Adams's anti-states' rights policies . Jackson selected Calhoun as his running mate, and together they defeated Adams and his running mate Richard Rush . Calhoun thus became the second of two vice presidents to serve under two different presidents . The only other man who accomplished this feat was George Clinton, who served as Vice President from 1805 to 1812 under Thomas Jefferson and James Madison . </P> <P> Early in Jackson's administration, Floride Calhoun organized Cabinet wives (hence the term "petticoats") against Peggy Eaton, wife of Secretary of War John Eaton, and refused to associate with her . They alleged that John and Peggy Eaton had engaged in an adulterous affair while she was still legally married to her first husband, and that her recent behavior was unladylike . The allegations of scandal created an intolerable situation for Jackson . The Petticoat affair ended friendly relations between Calhoun and Jackson . </P> <P> Jackson sided with the Eatons . He and his late wife Rachel Donelson had undergone similar political attacks stemming from their marriage in 1791 . The two had married in 1791 not knowing that Rachel's first husband, Lewis Robards, had failed to finalize the expected divorce . Once the divorce was finalized, they married legally in 1794, but the episode caused a major controversy, and was used against him in the 1828 campaign . Jackson saw attacks on Eaton stemming ultimately from the political opposition of Calhoun, who had failed to silence his wife's criticisms . The Calhouns were widely regarded as the chief instigators . </P> <P> Eaton took his revenge on Calhoun . In 1830, reports had emerged accurately stating that Calhoun, as Secretary of War, had favored censuring Jackson for his 1818 invasion of Florida . These infuriated Jackson . For reasons unclear, Calhoun asked Eaton to approach Jackson about the possibility of Calhoun publishing his correspondence with Jackson at the time of the Seminole War . Eaton did nothing . This caused Calhoun to believe that Jackson had approved the publication of the letters . Calhoun published them in the United States Telegraph, a newspaper edited by a Calhoun protégé, Duff Green . This gave the appearance of Calhoun trying to justify himself against a conspiracy to damage him, and further enraged the President . </P>
