Article I, Section 3, Clause 6:
The Senate shall have the sole Power to try all Impeachments. When sitting for that Purpose, they shall be on Oath or Affirmation. When the President of the United States is tried, the Chief Justice shall preside: And no Person shall be convicted without the Concurrence of two thirds of the Members present.
The Senate enjoys broad discretion in establishing procedures to be undertaken in an impeachment trial. For instance, in a lawsuit challenging the Senate’s use of a trial committee to take and report evidence, the Supreme Court in Nixon v. United States unanimously ruled that the suit posed a nonjusticiable political question and was not subject to judicial resolution.[1](https://www.law.cornell.edu/constitution-conan/article-1/section-3/clause-6/impeachment-trial-practices#fn1art1 " 506 U.S. 224, 238 (1993). ") The Court explained that the term “try” in the Constitution’s provisions regarding impeachment was textually committed to the Senate for interpretation and lacked sufficient precision to enable a judicially manageable standard of review.[2](https://www.law.cornell.edu/constitution-conan/article-1/section-3/clause-6/impeachment-trial-practices#fn2art1 " Id. at 229–30. ") In reaching this conclusion, the Court noted that the Constitution imposes three precise requirements for impeachment trials in the Senate: (1) Members must be under oath during the proceedings; (2) conviction requires a two-thirds vote; and (3) the Chief Justice must preside if the President is tried.[3](https://www.law.cornell.edu/constitution-conan/article-1/section-3/clause-6/impeachment-trial-practices#fn3art1 " Id. at 230. ") Given these three clear requirements, the Court reasoned that the Framers “did not intend to impose additional limitations on the form of the Senate proceedings by the use of the word ‘try.’” [4](https://www.law.cornell.edu/constitution-conan/article-1/section-3/clause-6/impeachment-trial-practices#fn4art1 " Id. ") Accordingly, subject to these three clear requirements of the Constitution, the Senate enjoys substantial discretion in establishing its own procedures during impeachment trials.
The Senate’s discretion to establish procedures for an impeachment trial extends to how the body will receive evidence. In addition to relying on the evidentiary record prepared by the House, Senate impeachment trials have generally involved the presentation of additional evidence by witnesses appearing before either the Senate or a trial committee. The different approaches adopted in past presidential impeachment trials, however, display the scope of the Senate’s discretion in this regard. In the trial of Andrew Johnson, the Senate took live testimony from more than forty witnesses.[5](https://www.law.cornell.edu/constitution-conan/article-1/section-3/clause-6/impeachment-trial-practices#fn5art1 " See Impeachment Trial of President Andrew Johnson, 1868, U.S. Senate, https://www.senate.gov/about/powers-procedures/impeachment/impeachment-johnson.htm (last visited Dec. 14, 2021). ")
In the trial of Bill Clinton the Senate chose to hear from three witnesses through videotaped depositions rather than through live questioning.[6](https://www.law.cornell.edu/constitution-conan/article-1/section-3/clause-6/impeachment-trial-practices#fn6art1 " See Proceedings of the United States Senate in the Impeachment Trial of President William Jefferson Clinton, Vol. III: Depositions and Affidavits, 106th Cong., 1st Sess., S. Doc. No. 106-4 (1999). The Senate also received three affidavits. Id. at 2534–36. ")
In contrast, the Senate chose not to obtain witness testimony in either of the two trials of Donald Trump.[7](https://www.law.cornell.edu/constitution-conan/article-1/section-3/clause-6/impeachment-trial-practices#fn7art1 " See Proceedings of the United States Senate in the Impeachment Trial of President Donald John Trump, Vol. II: Floor and Trial Proceedings, 116th Cong., S. Doc. No. 116-18, at 1498–99 (2020). In the second impeachment trial, the House Managers sought to obtain a Senate subpoena for testimony from Congresswoman Jaime Herrera Beutler (D-WA). The Senate approved a motion making it in order to debate such a subpoena, but the Senate instead agreed to a stipulation allowing introduction of Rep. Herrera Beutler’s existing public statement. 167 Cong. Rec. S717–19 (daily ed. Feb. 13, 2021). ")
While the Senate determines for itself how to conduct impeachment proceedings, the nature and frequency of Senate impeachments trial are largely dependent on the impeachment charges brought by the House. The House has impeached thirteen federal district judges, a judge on the Commerce Court, a Senator, a Supreme Court Justice, the secretary of an executive department, and three Presidents.[8](https://www.law.cornell.edu/constitution-conan/article-1/section-3/clause-6/impeachment-trial-practices#fn8art1 " See

(last visited Jan. 24, 2018). But the Senate ultimately has only convicted and removed from office seven federal district judges and a Commerce Court judge.[9](https://www.law.cornell.edu/constitution-conan/article-1/section-3/clause-6/impeachment-trial-practices#fn9art1 " See
