* On 2 January 1795, a Committee of Investigation reported to the Senate that, in their opinion, “the elections of Senators held in the counties of Washington, Allegheny, Westmoreland, and Fayette counties, during the late insurrection, [The so called “Whiskey Rebellion”] were not constitutional, and therefore not valid. The following day, the Senate voted on a strict party line vote to expel John Moore, William Todd, Thomas Stokely, and Absalom Baird from Senate and called for new elections to be held. The newly certified Senators took their seats in mid- February. Todd, Stokley, and Baird were returned to the seats previously vacated. Moore was replaced by Presly Carr Lane.
