Clause 5. The Senate shall chuse 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. 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. Clause 7. 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. Section 4. Clause 1. The Times, Places and Manner of holding Elections for Senators and Representatives, shall be prescribed in each State by the Legislature thereof; but the Congress may at any time by Law make or alter such Regulations, except as to the Places of chusing Senators. Federal Legislation Under This Clause Not until 1842 did Congress undertake to exercise the power to regulate the "times, places and manner of holding elections for Senators and Representatives." In that year it passed a law requiring the election of Representatives by districts.[139] Prior to that time some of the States had sought to increase their influence by electing all of their Representatives on a general ticket. The frequent deadlocks between the two Houses of State legislatures with respect to the election of Senators prompted Congress to pass a further act in 1866, which compelled the two bodies to meet in joint session on a specified day, and to meet everyday thereafter and vote for a Senator until one was elected.[140] The first comprehensive federal statute dealing with elections was adopted in 1870. Under the Enforcement Act of 1870 and kindred measures,[141] false registration, bribery, voting without legal right, making false returns of votes cast, interference in any manner with officers of election, and the neglect by any such officer of any duty required of him by State of federal law, were made federal offenses. Provision was made for the appointment by federal judges of persons to attend at places of registration and at elections with authority to challenge any person proposing to register or vote unlawfully, to witness the counting of votes, and to identify by their signatures the registration of voters and election tally sheets. After twenty-four years experience Congress repealed those portions of the Reconstruction legislation which dealt specifically with elections, but left in effect those dealing generally with Civil Rights.[142] As seen earlier, those sections have been invoked for the prosecution of election offenses which interfere with the rights of voters guaranteed
