The Senate “tries” all impeachments—it determines, on evidence presented, whether the charge in each Article of Impeachment is true, and whether, if the charge is true, the acts that are proven constitute an impeachable offense. Such an affirmative finding is called a “conviction” on the Article of Impeachment being voted upon. A two-thirds majority of the senators present is necessary for conviction.
