A conference committee, comprised of members from each chamber, works out the differences between the two versions of the bill.
Bill is returned to the House for a vote. No amendments allowed.
Bill is returned to the Senate for a vote. No amendments allowed.
Compromised version, approved by both chambers, sent to the President. He can sign it into law or veto it and return to Congress. Congress may override veto power with two-thirds majority vote in each chamber.
