If D.C. Council Chairman Kwame R. Brown is concerned about anything, it’s closure.

He used that word repeatedly in responding for the first time to allegations that the Office of Campaign Finance leveled Friday against his 2008 reelection campaign — including that it failed to report a combined $270,000 in contributions and expenditures.

“It brought it one step closer to closure,” Brown said of the complaint. “I’m looking forward to having closure to this. ... This four-year-old campaign issue is one step closer to being closed.”

Brown, speaking shortly after passing his first city budget as chairman, denied there had been any attempt to hide a $60,000 “side account” cited in the complaint, one that his brother Che Brown has control of.

“No one was hiding anything,” Brown said, noting that his campaign reported the “side account” when closing itself out with the campaign finance office. He added: “They said, ‘OK, you told us you had a second account, but you should have told us earlier you had a second account.’ ”

Brown maintained that there was no willful intent to violate campaign finance laws and that there is no basis for a criminal investigation. The D.C. Board of Elections and Ethics, which will adjudicate the matter, can refer the case to federal prosecutors.
