Sulaimon Brown's trial on the traffic charge was supposed to be Monday in D.C. Superior Court, but it was rescheduled to March 7.
Brown was arrested in September for driving with a suspended license. His Maryland license was suspended because of an unpaid parking ticket. His attorney has claimed Brown was treated unfairly because his license was suspended on July 4, when Motor Vehicle Departments in Maryland and the District were closed.
Brown has accused Mayor Vincent Gray's aides of paying him and promising him a job during last year's campaign to disparage then-Mayor Adrian Fenty. Federal authorities are investigating those claims.
