The beleaguered airports authority in charge of the $6 billion Dulles Rail project on Wednesday agreed to give the nation’s top transportation official broader oversight powers to monitor the authority’s recovery from a series of ethical and contracting scandals.

The Metropolitan Washington Airports Authority voted to allow U.S. Transportation Secretary Ray LaHood “full access at any time” to the authority’s “books, records, contracts, and documents.” The new agreement also gives LaHood veto power over any future changes made to the authority’s new ethics policy.
