In congress, who has the right to unlimited debate and unlimited opportunity to offer amendments

In Congress, those who have the right to unlimited debate and unlimited opportunity to offer amendments are the senators.

Explanation:

Revisions to the House of Representatives' rules limited debate in that House due to the growing number of members. In the Senate, as it is a smaller house, unlimited debate remained unchanged on the grounds that a senator should have the right to speak as long as he or she consideres necessary.

In the same way, another main feature of the Senate is that its members usually have the right to offer an unlimited number of amendments.

a phrase from a poem by ralph waldo emerson about the battle of lexington and concord. emerson's words read, “here once the embattled farmers stood / and fired the shot heard round the world.”
