Before Vincent C. Gray’s corrupt 2010 campaign, there was Lottery I. That 2008, multimillion-dollar procurement was marked by unethical behaviors and political interference. Now, a federal grand jury is probing whether bribery played a role.

Meanwhile, the fight continues between the District and Eric Payne, the senior procurement manager for Chief Financial Officer Natwar Gandhi, who handled Lottery 1. Payne, one of the few persons who acted with integrity, resisted efforts to alter the results of a competitive process, which the contracts appeal board ruled had been fair and proper.
