Clause 4: Adjournment.

Neither House, during the Session of Congress, shall, without the Consent of the other, adjourn for more than three days, nor to any other Place than that in which the two Houses shall be sitting.

Neither House may adjourn, without the consent of the other, for more than three days. Often, a House will hold pro forma sessions every three days; such sessions are merely held to fulfill the constitutional requirement, and not to conduct business. Furthermore, neither House may meet in any place other than that designated for both Houses (the Capitol), without the consent of the other House.

Section 6: Compensation, privileges, and restrictions on holding civil office.

Clause 1: Compensation and legal protection.

The Senators and Representatives shall receive a Compensation for their Services, to be ascertained by Law, and paid out of the Treasury of the United States. They shall in all Cases, except Treason, Felony and Breach of the Peace, be privileged from Arrest during their Attendance at the Session of their respective Houses, and in going to and returning from the same; and for any Speech or Debate in either House, they shall not be questioned in any other Place.

Senators and representatives set their own compensation. Under the Twenty-seventh Amendment, any change in their compensation will not take effect until after the next congressional election. Paying senators and representatives out of the federal treasury was a departure from the practice under the Articles of Confederation, where they were paid by the state in which they were elected.

Members of both houses have certain privileges, based on those enjoyed by the members of the British Parliament. Members attending, going to or returning from either house are privileged from arrest, except for treason, felony or breach of the peace. One may not sue a senator or representative for slander occurring during Congressional debate, nor may speech by a member of Congress during a Congressional session be the basis for criminal prosecution. The latter was affirmed when Mike Gravel published over 4,000 pages of the Pentagon Papers in the Congressional Record, which might have otherwise been a criminal offense. This clause has also been interpreted in Gravel v United States, (1972) to provide protection to aides and staff of sitting members of Congress, so long as their activities relate to legislative matters.

Clause 2: Independence from the executive.

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 increased 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.

Senators and representatives may not simultaneously serve in Congress and hold a position in the executive branch. This restriction is meant to protect legislative independence by preventing the president from using patronage to buy votes in Congress. It is a major difference from the Westminster political system in the British Parliament as well as those of some other nations using the parliamentary system, where cabinet ministers are required to be members of parliament.

Furthermore, senators and representatives cannot resign to take newly created or higher-paying political positions; rather, they must wait until the conclusion of the term for which they were elected. If Congress increases the salary of a particular officer, it may later reduce that salary to permit an individual to resign from Congress and take that position (known as the Saxbe fix).
