American legislative power:

Congress passes legislation, approves the government's annual budget and appropriation, approves its important domestic and foreign policies such as taxation, trade, conscription, finance, and approves treaties and agreements concluded by the government and the president with foreign governments and international institutions, and decides war and peace.

Congress can only amend the constitution on the proposal of more than two-thirds of the members of the House and Senate, and constitutional amendments can only be implemented with the approval of more than three-quarters of the state legislatures.

Congress also has the power to propose, consider and pass a large number of resolutions that do not require the president's signature.

The legislative power of the U.S congress and its legislative system;

If the president signs the bill, it will have the force of law and become law. If the president vetoes the bill, the House of Representatives can amend the bill to gain the president's support, or override the president's veto by a two-thirds majority (without abstaining) to make the bill automatically become law.

If the Congress reaches the President in less than ten days, and the President does not sign it during the session, the bill will be shelved and automatically become invalid (that is, pocket veto). Parliament can reintroduce the bill at the next meeting.

When voting on any bill, as long as there is a requirement of attendance 1/5, the names of voters and their voting results shall be published in the newspaper of the college for voters' supervision.
