The house impeached William Belknap, he resigned & the senate held a trial.
William W. Belknap
Starting on April 5, 1876, Belknap was tried by the Senate. For several weeks Senators argued over whether the Senate had jurisdiction to put Belknap on trial since he had already resigned office in March. Belknap's defense managers argued that the Senate had no jurisdiction; the Senate ruled by a vote of 37–29 that it did. Belknap was charged with five articles of impeachment, and the Senate listened to over 40 witnesses. With 40 votes needed for conviction, the Senate voted 35 to 25 to convict Belknap, with one Senator not voting, thus acquitting Belknap of all charges by failing to reach the required two-thirds majority. All Senators agreed that Belknap took the money from Marsh, but 23 who voted for acquittal believed that the Senate did not have jurisdiction. Grant's speedy acceptance of Belknap's resignation undoubtedly saved him from conviction.
