1. The Senate of the United States shall be composed of two senators
from each State, chosen by the legislature thereof, for six years; and
each senator shall have one vote.
2. Immediately after they shall be first assembled, in consequence of
the first election, they shall be divided, as equally as may be, into
three classes. The seats of the senators of the first class shall be
vacated at the expiration of the second year; of the second class, at
the expiration of the fourth year; and of the third class, at the
expiration of the sixth year; so that one-third may be chosen every
second year; and if vacancies happen, by resignation or otherwise,
during the recess of the legislature of any State, the executive thereof
may make temporary appointment until the next meeting of the
legislature, which shall then fill such vacancies.
3. No person shall be a senator who shall not have attained to the age
of thirty years, and been nine years a citizen of the United States, and
who shall not, when elected, be an inhabitant of that State for which he
shall be chosen.
4. The Vice-President of the United States shall be President of the
Senate, but shall have no vote, unless they be equally divided.
5. The Senate shall choose their other officers, and also a President,
_pro tempore_, in the absence of the Vice-President, or when he shall
exercise the office of President of the United States.
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.
7. Judgment, in case of impeachment, shall not extend further than to
removal from office, and disqualification to hold and enjoy any office
of honour, 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.
