Question: Where must revenue bills originate in the governing body that sets the salaries for Senate and House Members?

<P0-S0> at the federal level, article two of the united states constitution states in section 4 that ``the president, vice president, and all civil officers of the united states shall be removed from office on impeachment for, and conviction of, treason, bribery, or other high crimes and misdemeanors. <P0-S1> ''the house of representatives has the sole power of impeaching, while the united states senate has the sole power to try all impeachments. <P0-S2> the removal of impeached officials is automatic upon conviction in the senate. <P0-S3> in nixon v. united states (1993), the supreme court determined that the federal judiciary can not review such proceedings. <SEP> <P1-S0> As of December 2014, the annual salary of each Representative is $174,000. <P1-S1> The Speaker of the House and the Majority and Minority Leaders earn more: $223,500 for the Speaker and $193,400 for their party leaders (the same as Senate leaders). <P1-S2> A cost - of - living - adjustment (COLA) increase takes effect annually unless Congress votes to not accept it. <P1-S3> Congress sets members' salaries; however, the Twenty - seventh Amendment to the United States Constitution prohibits a change in salary (but not COLA) from taking effect until after the next election of the whole House. <P1-S4> Representatives are eligible for retirement benefits after serving for five years. <P1-S5> Outside pay is limited to 15% of congressional pay, and certain types of income involving a fiduciary responsibility or personal endorsement are prohibited. <SEP> <P2-S0> The Origination Clause, sometimes called the Revenue Clause, is part of Article I of the United States Constitution. <P2-S1> This clause says that all bills for raising revenue must start in the House of Representatives, but the Senate may propose or concur with amendments as in the case of other bills. <SEP> <P3-S0> The proceedings unfold in the form of a trial, with each side having the right to call witnesses and perform cross-examinations. <P3-S1> The House members, who are given the collective title of managers during the course of the trial, present the prosecution case, and the impeached official has the right to mount a defense with his own attorneys as well. <P3-S2> Senators must also take an oath or affirmation that they will perform their duties honestly and with due diligence. <P3-S3> After hearing the charges, the Senate usually deliberates in private. <P3-S4> The Constitution requires a two thirds super majority to convict a person being impeached. <SEP> <P4-S0> the chamber of deputies has 630 elected members, while the senate has 315 elected members. <P4-S1> the number of deputies and senators was fixed by a constitutional amendment in 1963: in its original text, the constitution provided for a variable number of members of parliament depending on the population. <P4-S2> the senate of the republic also includes, in addition to the elected senators, a small number of unelected members (senators for life). <P4-S3> there are two categories of senators for life. <P4-S4> former presidents of the republic are senators for life by law, unless they renounce this privilege. <P4-S5> furthermore, the president of the republic can appoint up to five italian citizens as senators for life "for outstanding merits in the social, scientific, artistic or literary field".different voting ages are mandated for each house: any italian citizen who is 18 or older can vote in the election of the chamber of deputies, while the voting age for the senate of the republic is 25. similarly, the two houses have a different age of candidacy: deputies are required to be 25 or older, while elected senators must be 40 or older. <P4-S6> no explicit age limit is required to be appointed senator for life (but presidents of the republic must be 50 or older).
