WASHINGTON, DC (WUSA) -- Prosecutors investigating DC Mayor Vincent Gray's campaign are getting the full cooperation of one of the key players.
Sources tell 9News Now that Howard Brooks, a key staffer in the Gray campaign, has worn a wire for prosecutors. Others have refused to wear a wire. Brooks recorded at least one conversation for federal prosecutors, according to sources.
It's not clear if Brooks has agreed to any kind of plea agreement in exchange for his cooperation.
Howard Brooks was named by Sulaimon Brown as one of the people in the Gray campaign who gave him money in exchange for his repeated public criticism of then-Mayor Adrian Fenty during the mayoral campaign debates.
Sulaimon Brown says he was also promised a job which he got and was then fired from.
Mayor Gray on Monday repeated what he has said since winning office this year-- that if there were any irregularities in his campaign they happened without his knowledge.
