Article I of the US Constitution establishes the Legislative Branch, consisting of the Senate and the House of Representatives.

The primary responsibility of the Legislative Branch is to enact laws, which are binding rules that govern the nation.

There are 100 members in the US Senate, with each state having two senators.

There are 435 members in the US House of Representatives, with the number of representatives from each state based on its population.

The term of office for a US Senator is 6 years, with one-third of the Senate up for election every two years.

The term of office for a US Representative is 2 years, with all members of the House up for election every two years.

A bill becomes a law through the process of introduction, committee consideration, floor vote, and presidential signature.

The President has the power of absolute veto, which allows them to reject a bill passed by Congress in its entirety.

Congress can override a presidential veto with a two-thirds majority vote in both the House and the Senate.

The principle of checks and balances in the US government involves the separation of powers among the three branches - legislative, executive, and judicial - to prevent any one branch from becoming too powerful.

The Legislative Branch, specifically the US Congress, has the power to declare war.

The Executive Branch, specifically the President, has the power to appoint Supreme Court justices, subject to confirmation by the Senate.

The Judicial Branch, specifically the federal courts, has the power to interpret laws and determine their constitutionality.

The separation of powers in the US government is designed to prevent tyranny by distributing power among the three branches and preventing any one branch from becoming too powerful.

A constitutional amendment requires a two-thirds majority vote in both the House and the Senate, followed by ratification by three-fourths of the states.
