"I earnestly invoke the attention of Congress to the consideration of such measures within its well-defined constitutional powers as will secure to all our people a free exercise of the right of suffrage and every other civil right under the Constitution and laws of the United States. No evil, however deplorable, can justify the assumption either on the part of the Executive or of Congress of powers not granted, but both will be highly blamable if all the powers granted are not wisely but firmly used to correct these evils. The power to take the whole direction and control of the election of members of the House of Representatives is clearly given to the General Government. A partial and qualified supervision of these elections is now provided for by law, and in my opinion this law may be so strengthened and extended as to secure on the whole better results than can be attained by a law taking all the processes of such election into Federal control. The colored man should be protected in all of his relations to the Federal Government, whether as litigant, juror, or witness in our courts, as an elector for members of Congress, or as a peaceful traveler upon our interstate railways."
