D.C. Council Chairman Kwame R. Brown will be deposed Monday as part of the Office of Campaign Finance investigation into how he used and accounted for money he raised in his 2008 reelection campaign.

Wesley Williams, a spokesman for the Office of Campaign Finance, said Brown (D) will be put under oath about 10 a.m. Monday in the office of his lawyer, Frederick Cooke.

“This is just part of the investigation,” Williams said.

Earlier this month, OCF released an audit that reported widespread irregularities in how Brown initially recorded several hundred thousand dollars in contributions and expenses. The audit also alleged that one of Brown’s campaign consultants subcontracted with his brother, Che, without the payments showing up on his campaign finance form.

Cooke declined to comment. But Williams said a “hearing officer, several attorneys and a court reporter” will be present at the deposition.

News of the deposition was first reported by blogger and activist Dorothy Brizill of DC Watch.

OCF is widely believed to be in the final stages of its investigation, which could result in Brown being fined. The matter could also be referred to the U.S. attorney’s office.
