Security Council Resolution 1973, as requested by the Transitional National Council, the Gulf Cooperation Council (GCC), and the Arab League. Terminates such authorization on the date on which the NATO mission ends or 180 days after the date of the enactment of this joint resolution, whichever occurs first. Declares that such authorization is intended to constitute specific statutory authority within the meaning of section 5(b) of the War Powers Resolution.

Directs the President to consult frequently with Congress regarding U.S. efforts in Libya, including by providing regular briefings and reports. Includes as elements in such briefings and reports: (1) an updated description of U.S. national security interests and policy objectives in Libya; (2) an updated list of U.S. Armed Forces activities in Libya; (3) an updated assessment of the opposition groups in Libya, including potential successor governments; and (4) an updated explanation of the President's legal and constitutional rationale for conducting military operations in Libya consistent with the War Powers Resolution.
