Questions about the Gray campaign’s finances and the Gray administration’s hiring practices are the subject of several investigations, including a probe by the U.S. attorney’s office. Here is where the other investigations stand:

●A D.C. Council special committee conducted hearings into Sulaimon Brown’s campaign allegations and the administration’s hiring practices. The committee concluded in August that “nepotism and cronyism” in the administration’s hiring practices violated local and federal law and damaged the city’s reputation. The probe did not find direct involvement by Mayor Vincent C. Gray in the administration’s most controversial personnel decisions.

●The House Committee on Oversight and Government Reform is continuing an investigation. “I expect that we’re going to be wrapping up not too far [from now], and we’ll be releasing our findings,” said a committee aide who requested anonymity. The aide said the panel had interviewed multiple witnesses and reviewed documents in the case.

●The Office of Campaign Finance announced that it would audit Gray campaign records after Brown’s allegations. That audit is continuing.
