WASHINGTON, DC (WUSA)-- 9NEWS NOW has obtained a new confidential report authorized by Mayor Vincent Gray's now-defunct transition team.
It turns out that the document, an amended due diligence report, reveals that former mayoral candidate and fired city employee Sulaimon Brown was once tried for attempted murder while living in Chicago.
The same confidential report, prepared by a company called Capitol Inquiry, says Brown was charged with assault in Essex County, New Jersey.
The 40-year-old Brown has grabbed major headlines recently after being hired then fired by the Gray administration.
Brown has charged he was promised a job by the Gray campaign in return for his repeated attacks against incumbent Mayor Adrian Fenty.
The accountant also charges he was paid cash in envelopes delivered by Gray campaign officials.
The FBI and staff on Capitol Hill have reportedly met with Brown. The U.S. Attorney's office is looking at his allegations.
Mayor Gray, his campaign chairman Lorraine Green and others deny all of Brown's allegations. Mayor Gray says he was only promised a job interview.
Brown was tried in 1988 and acquitted by a jury on the attempted murder charge in Chicago, according to the confidential report.
A grand jury failed to indict him on the assault charge in New Jersey.
A Gray associate told 9NEWS NOW on Monday the vetting firm failed to pick up this new information about Brown. Information that certainly should have prevented him from getting a job with the city.
After ignoring repeated calls for comment, Sulaimon Brown called 9NEWS NOW on Monday to correct an earlier online version of this story: the early story had said he was acquitted of "murder." It should have read "attempted murder."
Brown hung up, refusing to discuss more about the story.
