How Congress works
The Senate
100 senators, two from each state, serve six-year terms. About one-third are up for election every two years. The Senate confirms presidential nominees and approves treaties.

435 voting representatives, apportioned by population after each census, serve two-year terms. Six non-voting delegates represent D.C. and the territories. Revenue bills must start in the House.
house.govHow a bill becomes law
- A member of the House or Senate introduces a bill.
- The bill goes to a committee, which can hold hearings, amend it, and vote to report it.
- The full chamber debates and votes on it.
- The other chamber considers and passes the same bill, or the chambers work out a single version.
- The President signs it into law or vetoes it. Congress can override a veto with a two-thirds vote in both chambers.
