Transportation Secretary Ray LaHood praised leaders of the Metropolitan Washington Airports Authority on Wednesday for efforts to restore public confidence after a series of damaging revelations about top MWAA officials. Appearing at a meeting of the authority’s board of directors, LaHood said MWAA officials are making meaningful reforms.

LaHood traveled to MWAA headquarters at Reagan National Airport to administer the oath of office to two federal appointees to the board —  William Shaw McDermott, a Boston-based lawyer, and Nina Mitchell Wells, who served as New Jersey secretary of state from 1998 to 2004.
