Sulaimon Brown, the minor mayoral candidate whose allegations of corruption in D.C. Mayor Vincent Gray's 2010 campaign set off an ongoing federal investigation, has endorsed Councilwoman Anita Bonds in Tuesday's special election for an at-large council seat.

"Anita Bonds is a real Democrat, pure and simple," Brown said in an email. "Although she may not be the perfect person or candidate, she has good intentions, and her heart for our city is in the right place."

In a telephone call soon after a reporter posted the news of Brown's endorsement on Twitter, Bonds denied that she had sought his backing.

"I haven't seen the man or talked to him," Bonds said. "This is a shout-out from nowhere."

Asked if she would accept the endorsement, Bonds replied, "It's not whether I accept it. It's happened."

Brown said in March 2011 that the Gray campaign had paid him and promised him a job in exchange for his agreement to remain in the mayoral contest.

Brown contended that Gray's staff wanted him to criticize Adrian Fenty, the incumbent and Gray's rival, during candidate forums.

Those allegations prompted a federal investigation, and two Gray aides pleaded guilty in May to charges linked to the payments to Brown and the subsequent probe. Gray has not been charged and has denied wrongdoing.
