Article 1, Section 7, Clause 3: Resolutions

Every Order, Resolution, or Vote to which the Concurrence of the Senate and House of Representatives may be necessary (except on a question of Adjournment) shall be presented to the President of the United States; and before the Same shall take Effect, shall be approved by him, or being disapproved by him, shall be repassed by two thirds of the Senate and House of Representatives, according to the Rules and Limitations prescribed in the Case of a Bill.

This clause specifies that the procedures in the previous Presentation Clause apply to all joint Congressional actions, eliminating a possible loophole for carrying out Congressional actions without the President’s consent by casting them as something other than a bill.

In the narrow sense, a bill is a proposed law. Other acts of Congress, subject to the Resolutions Clause, include such things as declarations of war.

Two exceptions are provided for. The first is adjournment; Congress may vote to adjourn without Presidential consent, thus preventing the President from attempting to wear down a Congress by perpetually keeping it in session. The second exception is those orders, resolutions, or votes involving only a single house of Congress. In particular, the House may impeach without Presidential consent.  The Senate alone votes to confirm treaties or appointments, but since these already presumably have the approval of the President, this is somewhat moot. Likewise, since the Senate convicts on impeachment only by two-thirds majority, this is also somewhat moot.
