Under the U.S. Constitution, at least 67 senators must vote in favor of removing an impeached president from office. Article I of the Constitution states that while the House has the “sole power of impeachment,” the Senate has the power to “try all impeachment.” The president, vice president, and civil officers are all subject to impeachment, but in a presidential impeachment, the Constitution is specific about the process: the Chief Justice of the Supreme Court presides over the trial, and it takes a two-thirds majority to remove a president from office. Given the 100 members of the Senate, this works out to 67 votes (and no, the vice president cannot act as a tie-breaker in this one). A conviction by the Senate removes a president from office, and a second vote can bar an impeached president from running for or holding office in the future.
"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.
Judgment in Cases of Impeachment shall not extend further than to removal from Office, and disqualification to hold and enjoy any Office of honor, Trust or Profit under the United States: but the Party convicted shall nevertheless be liable and subject to Indictment, Trial, Judgment and Punishment, according to Law."
"[T]wo thirds of the Members present" is not necessarily 67 - it depends on how many Senators are present. 67 is the number, but only if all 100 Senators are present.
Without the need for any actual trial these days the new norm is 2/3 of Congress critters feel they should be able to erase 80,000,000 citizens votes at will.
actually, it is:
“And no Person shall be convicted without the Concurrence of two-thirds of the Members present.”
so, how many Repubs stay away to make 2/3 a reality?
