Beginning with the resolution adopted by the House of Representatives in 1827 which vested its Committee on Manufactures "with the power to send for persons and papers with a view to ascertain and report to this House such facts as may be useful to guide the judgment of this House in relation to a revision of the tariff duties on imported goods,"[93] the two Houses have asserted the right to inquire into private affairs when necessary to enlighten their judgment on proposed legislation. In Kilbourn _v._ Thompson,[94] the Court denied the right of Congress to pry into private affairs. Again, in Interstate Commerce Commission _v._ Brimson,[95] in sustaining a statute authorizing the Courts to use their process to compel witnesses to give testimony sought by the Commission for the enforcement of the act, the Court warned that, "neither branch of the legislative department, still less any merely administrative body, established by Congress, possesses, or can be invested with, a general power of making inquiry into the private affairs of the citizen."[96] Finally, however, in McGrain _v._ Daugherty,[97] the power of either House "to compel a private individual to appear before it or one of its committees and give testimony needed to enable it efficiently to exercise a legislative function belonging to it under the Constitution, * * *"[98] was judicially recognized and approved. PURPOSE OF INQUIRY In the absence of any showing that legislation was contemplated as a result of the inquiry undertaken in Kilbourn _v._ Thompson, the Supreme Court concluded that the purpose was an improper one--to pry into matters with which the judiciary alone was empowered to deal.[99] Subsequent cases have given the legislature the benefit of a presumption that its object is legitimate. In re Chapman[100] established the proposition that to make an investigation lawful "it was certainly not necessary that the resolutions should declare in advance what the Senate meditated doing when the investigation was concluded."[101] Similarly, in McGrain _v._ Daugherty, the investigation was presumed to have been undertaken in good faith to aid the Senate in legislating.[102] Going one step further in Sinclair _v._ United States,[103] which on its facts presented a close parallel to the Kilbourn Case, the Court affirmed the right of the Senate to carry on its investigation of fraudulent leases of government property after suit for the recovery thereof had been instituted. The president of the lessee corporation had refused to testify on the ground that the questions related to his private affairs and to matters cognizable only in the courts wherein they were pending and that the committee avowedly had departed from any inquiry in aid of legislation. The Senate prudently had directed the investigating committee to ascertain what, if any, other or additional legislation may be advisable. Conceding "that Congress is without authority to compel
