Newly elected D.C. Mayor Vincent Gray has called on the city’s top law enforcement officer to investigate allegations by former mayoral candidate Sulaimon Brown that Gray gave him a high-paying job in exchange for Brown’s support during the election. Gray vehemently denied the charges, but did concede he has made some big mistakes early in his tenure.

“We have made missteps,” Gray said. “We have taken steps to address those missteps.”
