Three separate investigations — by Robert Andary, the former watchdog of the Office of the Chief Financial Officer, an international law firm commissioned by the Metro board, and now the D.C. Board of Ethics and Government Accountability — have all come to the same conclusion: Councilman Jim Graham, D-Ward 1, violated the public trust when he improperly tried to influence the city’s lottery contract in 2008.

A preliminary investigation by the city’s ethics board found that Graham “committed one or more violations of the District of Columbia Code of Conduct” by trying to link the contract to a separate Metro development deal for the benefit of a campaign contributor.
