A CODEL, short for Congressional Delegation, is an official trip taken by one or more members of Congress to meet with foreign or domestic leaders, inspect government operations, or gather facts outside Washington. The term most often refers to overseas travel. Every CODEL is funded by taxpayers, authorized through a formal approval chain, and disclosed publicly once the delegation returns. If a trip is made entirely by congressional staff with no elected member aboard, it is a STAFFDEL rather than a CODEL.
Who Goes on a CODEL
A lead member organizes the trip, typically a committee chair or ranking member whose jurisdiction connects to the destination or subject. Other Senators or Representatives join based on committee assignments or a specific legislative interest in the region. Each participating lawmaker needs a documented official reason to be there.
The support team is substantial. Professional committee staff provide technical expertise and handle logistics. Military escorts manage security and transportation. State Department personnel coordinate diplomatic protocols and work with embassies at each stop. These roles matter because CODELs frequently move through active conflict zones or politically sensitive areas where logistics and security cannot be improvised.
How a CODEL Gets Authorized
A member of Congress cannot simply book a flight and label it official travel. International CODELs require written authorization from specific officials. In the House, the Speaker or the relevant committee chair can approve the trip. In the Senate, the President pro tempore, the majority and minority leaders, and committee chairs all hold authorization power.1Congress.gov.

How CODELs Are Paid For
Congressional committees draw on appropriated funds to cover transportation, lodging, and meals for the delegation. Using public money rather than private donations is a deliberate design choice, keeping lawmakers from becoming indebted to lobbyists or outside interests for their travel.
A separate mechanism covers local expenses abroad. Under 22 U.S.C. ยง 1754, foreign currencies already owned by the U.S. government can be made available to members and staff for day-to-day costs. When no U.S.-owned local currency exists in a particular country, the Treasury may purchase it. The statute caps these local-currency allowances at $75 per day per person or the maximum federal per diem rate for that country, whichever is greater, not counting transportation.2Office of the Law Revision Counsel. 22 USC 1754 – Foreign Currencies Actual per diem rates vary by destination, set by the State Department based on local costs.
Military or Commercial Aircraft
CODELs are often pictured on military jets, but Department of Defense policy sets commercial travel as the default. Military airlift cannot be used if commercial airline service, including charters, can reasonably meet the delegation’s schedule within a 24-hour window. Military aircraft become an option only when specific conditions are met: a clear and present danger to travelers, an emergency, cost-effectiveness compared to commercial alternatives, or other compelling operational reasons that make commercial travel unacceptable. When military aircraft are used, the Assistant Secretary of Defense for Legislative Affairs oversees the assignment and must approve the support.3Department of Defense. DoD Support for Travel of Members and Employees of Congress In practice, CODELs to war zones or unstable regions almost always qualify for military airlift; trips to allied nations in Western Europe or Asia often use commercial service.
What Delegations Do on the Ground
The work on a CODEL varies with the destination and the committee’s agenda, but a few categories recur.
Oversight and Fact-Finding
Members evaluate how American policy plays out on the ground and inspect foreign aid programs to see whether federal dollars are achieving intended results. These firsthand assessments feed decisions to expand, restructure, or cut international assistance.
Military Inspections
Delegations visit U.S. military installations and meet with troops stationed overseas. Members on armed services or appropriations committees use these visits to verify troop readiness, assess facilities, and evaluate defense spending. Base commanders tend to be more candid in person than in prepared testimony.
Diplomatic Engagement
Meetings with foreign heads of state, cabinet officials, and parliamentary counterparts form a major part of most international CODELs. The conversations cover trade agreements, security partnerships, and regional conflicts. Congress does not negotiate treaties directly, but the relationships built during these meetings shape how lawmakers vote on foreign policy legislation and international programs.
International Conferences
Members sometimes travel as part of U.S. representation at international conferences and multilateral forums on issues like climate, trade, or global health.
Family Travel
Spouses and immediate family members can accompany lawmakers on CODELs, but the rules limit who pays. For trips funded by appropriated dollars, the member must personally cover the cost of any non-official traveler. In the House, the member submits a check to the U.S. Treasury for the equivalent of a commercial first-class ticket for each family member, along with a written explanation. The names of all non-member passengers must appear on the travel voucher.
Programs funded by foreign governments add their own restrictions. Under the Mutual Educational and Cultural Exchange Act, a traveling member may not accept foreign-paid travel expenses for a spouse or dependent. Under the Foreign Gifts and Decorations Act, travel expenses for an accompanying spouse or dependent may be accepted. Spousal travel rules therefore depend on the specific funding source for each leg of the trip.
Post-Travel Disclosure
After a CODEL wraps up, transparency rules apply. The official who authorized the travel prepares a quarterly consolidated report that itemizes amounts spent in foreign currencies and their U.S. dollar equivalents. In practice, the committee chair, ranking member, or senior staff member files a single report covering the entire delegation rather than each participant reporting individually.1Congress.gov. Disclosure of International Travel by Congress The report breaks down per diem expenditures, transportation, and miscellaneous expenses, along with the reasons for each.
These disclosures are published in the Congressional Record and are open to public review.1Congress.gov.
