Congressional Foreign Travel Cost Disclosure Act - Requires the Secretary of Defense (DOD) to give a Member, officer, or employee of either chamber of Congress carrying out official duties outside the United States a written statement of the cost of any DOD-provided transportation within 10 days after completion of the trip. Requires such statement to also be: (1) provided to the congressional defense committee of such Member, officer, or employee; and (2) made available to the public for a four-year period.

Excludes from such requirements any trip whose sole purpose is to visit one or more U.S. military installations and/or to visit U.S. military personnel in a war zone.
