The Department of Housing & Urban Development will be in the barrel on Capitol Hill on Wednesday, when a committee will convene to investigate allegations that senior HUD officials violated federal law and obstructed investigators’ efforts to uncover potential wrongdoing.

The Oversight and Investigations Subcommittee will hold a hearing titled “Exploring Alleged Ethical and Legal Violations at the U.S. Department of Housing and Urban Development.”

The witnesses will be David Montoya, Inspector General of HUD, and Edda Emmanuelli Perez, Managing Associate General Counsel for Appropriations Law, Budget Issues and Financial Management and Assurance Teams in the Office of General Counsel at the Government Accountability Office.

Both the HUD-OIG and the GAO have recently investigated and reported on potential ethical and legal violations by senior HUD officials.

The most recent of these investigations relates to improper hiring and conflicts of interest, which were subjects of a HUD-OIG report dated August 20, 2014.

The second investigation relates to prohibited lobbying activities, which was the subject of a HUD-OIG report dated February 18, 2014, a subsequent Oversight and Investigations Subcommittee hearing dated February 26, 2014, and a legal memorandum from GAO dated September 9, 2014.
