However, the same bill will eventually have to pass both chambers. There is always one lead author on a bill and any number of co-authors. Committees are divided into areas of subject matter. For example, many pharmacy and health care bills will go to the Health Committees. Those bills that do proceed get a public hearing, are debated, and usually go through a revision period where amendments are offered.
Amendments can either increase or decrease the areas and issues that the bill affects.
The leaders of the chamber then schedule the bill for debate and a vote. Again, the bill is discussed, amendments can be offered, and the bill is eventually voted on. There it will go through a process similar to the one just mentioned. If this occurs the bill could go to a conference committee composed of members of each chamber. There they work out the differences.
