District campaign finance authorities announced Friday that they have filed a complaint against the 2008 reelection campaign of D.C. Council Chairman Kwame R. Brown (D).

The Office of Campaign Finance said in a news release that the 2008 Committee to Re-Elect Kwame R. Brown “is charged among other things, with failure to report 210 contributions totaling $102,763.00, failure to report 53 expenditures totaling $169,431.49 . . . and failure to substantiate $174,785.57 in expenditures.”

Brown’s attorney, Frederick D. Cooke Jr., declined to comment Friday.

The campaign finance office said that it filed the complaint Friday with the Board of Elections and Ethics after its investigation. The complaint appears to largely support the findings of an audit released in April. The audit suggested that about $240,000 in Brown campaign funds were sent through an intermediary to a company owned by his brother.

In an interview after the audit was released, Brown apologized for what he called “administrative errors” but stressed that all funds were accounted for and were spent on campaign-related expenses.

Brown responded to the audit’s findings during a two-hour deposition in May.

The campaign finance office said it “will present evidence of the violations” to the board, which will set a hearing on the charges “in the near future.”

The announcement caps a turbulent week in city politics, which started with an unusual hearing on allegations involving Mayor Vincent C. Gray (D) and new charges from the city’s attorney general that council member Harry Thomas Jr. (D-Ward 5) funneled more than $300,000 in city funds for his personal use. Brown, Gray and Thomas have all denied wrongdoing.
