What is a concurrent resolution?

A concurrent resolution, H. Con. Res. or S. Con. Res., is a proposal that requires the approval of both Chambers, but does not have the force of law and does not require the signature of the President. Concurrent resolutions may be introduced in either the House or the Senate and, upon approval by both, are signed by the Clerk of the House and the Secretary of the Senate. Generally, concurrent resolutions are introduced to make or amend rules that affect the operations of both Chambers or to express the sentiment of both Chambers. For example, a concurrent resolution may be introduced to set the time of Congress' adjournment or to convey the congratulations of Congress to another country on the anniversary of its independence.
