We all know that federal prosecutors are still looking into Mayor Vince Gray’s 2010 campaign, notably claims that campaign staffers paid fellow candidate Sulaimon Brown to attack Adrian Fenty and that they illegally accepted cash contributions and turned them into money orders.

But WUSA9 has one of the juiciest rumors to date, involving none other than Howard Brooks, a Gray campaign staffer who has remained a central focus of the federal probe:

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.

As you may recall, Brooks was allegedly one of the campaign staffers who handed Brown cash to continue his tirades against Fenty.

Beyond the sheer intrigue of this, plenty of questions remain. For one, what exactly could Brooks get on tape, and who could he get it from? Did he get Lorraine Green, who managed Gray’s campaign and transition, admitting to anything illegal? Or Gray himself? Or did the wire prove fruitless, having been used too late after the election and after all of the campaign’s main participants had lawyered up?

Like much of the investigation, we’ll likely only find out the full details if charges are brought against Gray’s campaign. If not, well, this will go down as just another scintillating nugget of news from the post-election scandals.
