The role that the senate has in the impeachment process is sole power to try-to judge, sit as a court-in impeachment cases.
The House of Representatives serves as a combination prosecutor/grand jury in that it both draws up the charges and votes whether to impeach the official on such charges. The House first appoints several Representatives as what are called "Managers" to draft the charges. Then the entire House votes on whether to impeach the official on the charges. If the vote is in the affirmative, the Managers handle presenting the evidence to the Senate or Senate Impeachment Committee.
Not every impeachment is put on trial.
