Basically, Rand's amendment serve to reaffirm the Constitution with regard to declarations of war and that NATO lacks the authority to supercede the US Congress.
The constitution is clear on such matters.
Paul proposed an amendment which would emphasise that only the U.S. Congress has the authority to declare war under the Constitution.
Paul's amendment, predictably, was immediately rejected by the committee.
Anyway. The Senators dialogue comes after the U.S. Senate committee backed the accession of Finland, Sweden to NATO.
The U.S. Senate Foreign Relations Committee on Tuesday backed Finland and Sweden's accession to NATO, paving the way for the full Senate to vote on the most significant expansion of the 30-member alliance since the 1990s.
