The former chief of the defunct Anacostia Waterfront Corp. and now a top aide to Philadelphia Mayor Michael Nutter is alleged to have committed an “ethics violation” by D.C. auditors for his role in a questionable real estate services contract.

Andrew Altman should have removed himself from any involvement in awarding “real estate project management services” in the area of Nationals Park because of his direct ties to the contractor, the D.C. inspector general concluded in a recent audit.
