<P> Although not specifically mentioned in the Constitution, Congress has also long asserted the power to investigate and the power to compel cooperation with an investigation . The Supreme Court has affirmed these powers as an implication of Congress's power to legislate . Since the power to investigate is an aspect of Congress's power to legislate, it is as broad as Congress's powers to legislate . However, it is also limited to inquiries that are "in aid of the legislative function;" Congress may not "expose for the sake of exposure ." It is uncontroversial that a proper subject of Congress's investigation power is the operations of the federal government, but Congress's ability to compel the submission of documents or testimony from the President or his subordinates is often - discussed and sometimes controversial (see executive privilege), although not often litigated . As a practical matter, the limitation of Congress's ability to investigate only for a proper purpose ("in aid of" its legislative powers) functions as a limit on Congress's ability to investigate the private affairs of individual citizens; matters that simply demand action by another branch of government, without implicating an issue of public policy necessitating legislation by Congress, must be left to those branches due to the doctrine of separation of powers . The courts are highly deferential to Congress's exercise of its investigation powers, however . Congress has the power to investigate that which it could regulate, and the courts have interpreted Congress's regulatory powers broadly since the Great Depression . </P> <P> The House of Representatives shall be composed of Members chosen every second Year by the People of the several States, and the Electors in each State shall have the Qualifications requisite for Electors of the most numerous Branch of the State Legislature . </P> <P> Section Two provides for the election of the House of Representatives every second year . Since Representatives are to be "chosen...by the People," State Governors are not allowed to appoint temporary replacements when vacancies occur in a state's delegation to the House of Representatives; instead, the Governor of the state is required by clause 4 to issue a writ of election calling a special election to fill the vacancy . </P> <P> At the time of its creation, the Constitution did not explicitly give citizens an inherent right to vote . Rather, it provided that those qualified to vote in elections for the largest chamber of a state's legislature may vote in Congressional (House of Representatives) elections . Since the Civil War, several constitutional amendments have been enacted that have curbed the states' broad powers to set voter qualification standards . Though never enforced, clause 2 of the Fourteenth Amendment provides that when the right to vote at any election for the choice of electors for President and Vice President of the United States, Representatives in Congress, the Executive and Judicial officers of a State, or the members of the Legislature thereof, is denied to any of the male inhabitants of such State, being twenty - one years of age, and citizens of the United States, or in any way abridged, except for participation in rebellion, or other crime, the basis of representation therein shall be reduced in the proportion which the number of such male citizens shall bear to the whole number of male citizens twenty - one years of age in such State . The Fifteenth Amendment prohibits the denial of the right to vote based on race, color, or previous condition of servitude . The Nineteenth Amendment prohibits the denial of the right to vote based on sex . The Twenty - fourth Amendment prohibits the revocation of voting rights due to the non-payment of a poll tax . The Twenty - sixth Amendment prohibits the denial of the right of US citizens, eighteen years of age or older, to vote on account of age . </P>
