Controversy over proposed expansion of National Airport.

Leaders of a Senate committee have tentatively agreed to add four long-distance flights at Reagan National Airport, despite opposition from D.C.-area lawmakers and the airport's management. The deal is part of a broader aviation bill Congress needs to pass by the fall. The Senate deal would need to pass other hurdles before it could become law. The House Transportation Committee advanced its own version of the aviation bill Wednesday with bipartisan support, but it does not address the issue of flights at National.
