D.C. Council member Michael A. Brown, who is running for reelection in November, filed updated campaign finance statements with city officials last week. The report identifies $113,950 as “unexplained expenditures” from July 2011 through June, meaning it is unclear how the funds were spent. Brown has dismissed his campaign treasurer, who last week denied any wrong doing. The disclosure is the latest in a string of controversies surrounding Brown’s campaign and his personal finances.
