To the Senate of the United States:
I have received and taken into respectful consideration the resolution of the Senate of yesterday, adopted in executive session, requesting information in regard to supposed negotiations between the United States and Great Britain and between the United States and the Republics of Nicaragua and Costa Rica, respectively. Any information which may be in the possession of the Executive on these subjects shall in due time be laid before the Senate, but it is apprehended that it would not comport with the public interests to communicate it under existing circumstances.
MILLARD FILLMORE.
