Michael Brown, a former D.C. Council member who pleaded guilty in June to accepting bribes, faces more jail time after prosecutors uncovered new evidence of campaign finance violations.

In a new plea deal signed today, Brown admitted accepting more than $100,000 in secret funding to support his campaign in 2008 for an at-large D.C. Council seat. Under the terms of the new plea agreement, Brown, who hasn’t been sentenced, faces up to 43 months in jail instead of the 37 months in the original deal.
