Mr. JACKSON.--As, Mr. Speaker, this subject is novel in its nature, and may be important in its consequences, I presume there exists a disposition to hear the reasoning which any gentleman may be disposed to offer upon it. It is with this view that I rise to express my opinion in favor of creating a committee of inquiry. I consider this House as the grand inquest of the nation, whose duty it is to inquire, on a proper representation, into the conduct of every official character under the Government. Like a grand jury, we ought, in my opinion, at the instance of any member, to send for all persons possessed of information calculated to throw light upon the conduct of any individual inculpated. A contrary doctrine would lead to the most unfortunate consequences. It would lead to this, that a minority would never be able to inquire into the conduct of a State offender, unless such inquiry were favored by the majority. As it is now contended that the inquiry is not a matter of right which any member may demand, but a matter of favor, to be granted according to the pleasure of the majority, it may be said that, if a majority favor an individual, he will always escape without an impeachment. But I believe otherwise; and that the Senate, like a virtuous judge, will not suffer an atom of prejudice or partiality to fall into the scales of justice. But, say gentlemen, though it may be the duty of the House to impeach an officer, it is necessary that facts, warranting such an impeachment, should be first presented. This is not the course pursued in cases where a grand jury is called upon to act. If a murder is committed, it is their duty to inquire, and diligently inquire, who is guilty of the act, and to send for all persons capable of giving information respecting it. Such is the practice. If it shall be required to furnish facts, as is urged by gentlemen, the consequence will be that offences of the highest nature will be committed with impunity. It has been observed that it is odious to undertake the task of a public informer. But what the constitution and laws make our duty, so far from being odious, is honorable; because we thereby discharge a duty imposed upon us by our oaths, and because we show ourselves unawed by the vicious conduct of bad men. If the character of a public informer be odious, are we to expect that private individuals will come forward with affidavits? In such a case, to say the least of it, the duty would be of an unpleasant nature.
