"Legislators are immune from deterrents to the uninhibited discharge of their legislative duty, not for their private indulgence but for the public good. One must not expect uncommon courage even in legislators".[189] Clause 2. No Senator or Representative shall, during the Time for which he was elected, be appointed to any civil Office under the Authority of the United States, which shall have been created, or the Emoluments whereof shall have been encreased during such time; and no Person holding any Office under the United States, shall be a Member of either House during his Continuance in Office. INCOMPATIBLE OFFICES According to legislative precedents, visitors to academies, regents, directors and trustees of public institutions, and members of temporary commissions who receive no compensation as such, are not officers within the constitutional inhibition of section 6.[190] Government contractors and federal officers who resign before presenting their credentials may be seated as Members of Congress.[191] In 1909, after having increased the salary of the Secretary of State,[192] Congress reduced it to the former figure so that a Member of the Senate at the time the increase was voted would be eligible for that office.[193] The first clause again became a subject of discussion in 1937, when Justice Black was appointed to the Supreme Court in face of the fact that Congress had recently improved the financial position of Justices retiring at seventy and the term for which Mr. Black had been elected to the Senate from Alabama in 1932 had still some time to run. The appointment was defended by the argument that inasmuch as Mr. Black was only fifty-one years old at the time and so would be ineligible for the "increased emolument" for nineteen years, it was not _as to him_ an increased emolument.[194] Section 7. Clause 1. All Bills for raising Revenue shall originate in the House of Representatives; but the Senate may propose or concur with Amendments as on other Bills.
