He was also Minister to Russia under Andrew Jackson in 1830. After serving as President Thomas Jefferson's spokesman in the House, he broke with the president in 1805 as a result of what he saw as the dilution of traditional Jeffersonian principles as well as perceived mistreatment during the impeachment of Samuel Chase, in which Randolph served as chief prosecutor. Following this split, Randolph proclaimed himself the leader of the "Old Republicans" or "Tertium Quids", a wing of the Democratic-Republican Party who wanted to restrict the role of the federal government. Specifically, Randolph promoted the Principles of '98, which said that individual states could judge the constitutionality of central government laws and decrees, and could refuse to enforce laws deemed unconstitutional.
