At the age of 14, in 1825, Benjamin entered Yale College, an institution popular among white Southerners; Vice President John C. Calhoun, a South Carolinian, was among its alumni. Although Benjamin was successful as a student at Yale, he left abruptly in 1827 without completing his course of study. The reasons for this are uncertain: In 1861, when Louisiana left the Union and Benjamin resigned as a U.S. senator, an abolitionist newspaper alleged that he had been caught as a thief at Yale. He considered bringing suit for libel but litigation was impractical. In 1901, his sole surviving classmate wrote that Benjamin had been expelled for gambling. One of his biographers, Robert Meade, considered the evidence of wrongdoing by Benjamin to be "too strong to be ignored", but noted that at the time Benjamin left Yale, he was only 16 years old.
