Council member Mary Cheh (D-Ward 3) gavels another D.C. Council hearing on Thursday into the controversy over hiring practices by the administration of Vincent C. Gray, and allegations by a former mayoral candidate that Gray's campaign paid him to attack then-mayor Adrian M. Fenty.

About 10 witnesses are expected to testify before the council's Committee on Government Operations and the Environment. The witness list includes Sulaimon Brown, who alleged he received payments from Gray campaign chairwoman Lorraine Green and campaign consultant Howard Brooks; Leslie Green, Lorraine's daughter and one of several children of campaign staffers or administration officials who were hired by the administration; Linda Wharton Boyd, the mayor's communications chief; Gerri Mason Hall, who Gray recently dismissed as his chief of staff; and Brooks.

Gray, Green and Brooks have denied Brown's allegations. The Washington Post has not been able to confirm any of the alleged payments.

The Gray administration hired Brown as a $110,000-a-year special assistant in the Department of Health Care Finance. He was subsequently fired after news reports of past legal troubles.

The hearing is expected to last most of the day, and it's the second of three to be held. Last week, the council heard testimony from Talib Karim, who resigned as chief of staff of the Department of Health Care Finance following Brown's dismissal; and Judy Banks, the now former interim director of the Department of Human Resources, among others. In the next few weeks, the council is expected to hear from Lorraine Green as well.
