You can call your representative or senator and ask when a specific hearing will be held.
Hearings are a presentation of information on a bill or on a specific issue.
Those testifying at hearings in Congress usually are considered to be experts on the issue, but, many times, ordinary citizens present their views or personal stories about the issue or how a bill will affect their lives. You can request the written testimony offered at a hearing by calling your Congressperson or the specific committee that held the hearing. Furthermore, you can influence legislators and their votes at various times during the life of a bill. You can keep a bill from dying in committee or help the bill be brought out favorably from committee by calling or writing to your legislator. A crucial time when your legislator needs to hear from you is before a floor vote in either chamber.
