You may be familiar with the laws that govern your daily life, but it is often a mystery for some citizens to fully understand how these laws are created and introduced. With so many terms (bill, law, committee, Congress) the process can indeed be confusing, but in fact the way a bill becomes law it quite clear and methodical.
A bill, or simply a suggested law, can be introduced by any member of Congress (that is to say, either in the Senate or the House of Representatives). From there, the bill gets discussed in an appropriate committee where it is modified and voted upon. If the committee is in favor of the bill, then it moves to both the Senate and the House for debate. If either body rejects the bill, it dies in its current state. If the bills are approved, they go to a conference committee, which seeks to iron out any differences that may exist between the two versions. From there, the consensus bill is sent back to Congress where it is voted upon again. Once the bill makes it out of Congress, the President either signs it (and thus a law is born) or vetoes it.
