      • bill is revised during the committee process
      • includes hearings to determine why a law is needed in the first place
      • after a hearing, the committee votes on whether it should be sent to the full chamber
    • when a bill passes one chamber, it is forwarded to the other chamber
    • once a bill passes both chambers, it goes to a conference committee
      • made of both senators’ and house’ versions of the bills
      • cannot substantially change the bills
      • but tries to reach a compromise on both versions
      • when the committee reaches a resolution, each chamber votes on the bill again
      • if the original conference committee cannot reach an agreement:
        • the bill may be assigned to a new conference committee
        • or go back into committees of each chamber for more revisions
    • all bills that pass in Congress are signed by:
      • Speaker of House of Representatives
      • the president of the Senate
