The power of this House has been asserted to be similar to that of a grand jury; this seems to be conceded on both sides, but though it bears a resemblance, it was not strictly so--it was more extensive. Grand juries were authorized to present such indictments or such complaint or information as were submitted to them by the Attorney General, or which they knew of their own knowledge. The attorney also inquires if there is probable ground for the complaint, and brings the witnesses before the jury, who examine them to establish the facts alleged; but this House has no officers authorized to make inquiry and bring forward the business in due form; therefore the House possess both the power of the Attorney General and the grand jury, with relation to impeachment; for where a power of decision is given, all the powers necessary to carry that decision into effect are implied. The making inquiry, procuring witnesses, or other testimony, and preparing the case in due form, is the object of the resolution; and if the House does not do it in this or some other such method, there is no other agent authorized to do it. With respect to precedent and parliamentary usage, Mr. F. said he had formerly examined many, but was not prepared to state them at this time, and did not think them necessary on this occasion. In all the examples of impeachment by the British Parliament, from the reign of Henry VIII., when parliamentary power was reduced to a mere shadow, till the present time, when the parliamentary power has been amply enlarged and established, and their proceedings become more uniform, there will be shades of difference found in all of them, arising from various circumstances; we have few precedents of our own, and of these few none of them apply to the present case. It is the constitutional duty of this House to impeach, when impeachment is necessary, and of the Senate to decide on impeachments; but with respect to the manner in which each House should proceed, they are not trammelled by forms nor entangled in precedents.
