According to the most recent report filed with the D.C. Office of Campaign Finance, Brown’s campaign has taken in nearly $148,000 and has spent about $32,000. The campaign reported having $115,515 on hand as of the June 10 reporting period. Records show Brown spent $12,061 during the last reporting, including four $2,400 payments to a man identified by campaign officials as the landlord for Brown’s office.

Brown, son of the late commerce secretary Ronald H. Brown, is seeking reelection to one of two at-large council seats on the ballot in the Nov. 6 election.

Two weeks ago, Brown scored a major political victory when his colleagues elected him president pro temp of the council in the body’s leadership shuffle after Kwame Brown’s resignation.

But Michael Brown is still expected to face a stiff challenge as he continues to be battered by questions about his personal finances.

In January 2011, The Washington Post reported that he and his wife had failed to make timely property tax payments on their $1.4 million Chevy Chase home. In April 2011, the Internal Revenue Service filed a $50,000 lien against Brown for failure to pay income taxes dating to 2004.

According to a copy of the lien, Brown failed to pay $7,128 in 2004, $28,625 in 2005, $5,176 in 2007 and $11,951 in 2008. A fresh IRS lien was filed in April for $20,000 in income-tax obligations through 2010.

D.C. Superior Court records also indicate that Brown missed rent payments on two apartments that have been under his name at the Rittenhouse Apartments on 16th Street NW over the past two years. The complaints were dropped after Brown satisfied his account.

One of Brown’s campaign opponents, David Grosso, tweeted Thursday that Brown “can’t handle money in any aspect of his life — personal, campaign and of course legislative.”

But aides to Brown said that his discovery of the campaign discrepancies and decision to make the matter public demonstrate his commitment to transparency and accountability.

“We believe the fact that the alleged theft was discovered by the candidate reflects well on Michael Brown’s financial oversight,” said L. Asher Corson, Brown’s campaign spokesman.
