Democratic (constitutionalist) Senators Clement C. Clay, Jr. and Benjamin Fitzpatrick of Alabama, David Yulee and Stephen Mallory of Florida, and Jefferson Davis of Mississippi, all withdraw from the Senate.  In his farewell address, Davis says,

       Nullification is a remedy which it is sought to apply within the [voluntary] Union, and against the agent of the States.  It is only to be justified when the agent has violated his constitutional obligation, and a State, assuming to judge for itself, denies the right of the agent thus to act, and appeals to the other States of the [voluntary] Union for a decision; but when the States themselves, and when the people of the States, have so acted as to convince us that they will not regard our constitutional rights, then, and then for the first time, arises the doctrine of secession in its practical application.
