There’s Sulaimon Brown, the onetime mayoral candidate who says he was promised a job by Gray’s campaign if Brown helped publicly smear former mayor Adrian Fenty. There’s Howard L. Brooks, the campaign consultant who allegedly mishandled donations and has ties to District lottery disputes. And there’s Lorraine A. Green, Gray’s campaign chairwoman who allegedly promised Brown a job.

Then there are the people listed as money-order donors who say they knew nothing about said donations to Gray’s campaign, not to mention the mayor himself.
