WASHINGTON (CBSDC) - A judge has agreed not to sentence former D.C. Mayor Vincent Gray campaign aide Thomas Gore, at least for the time being.

Gore was in U.S. District Court Tuesday morning for a status conference just months after pleading guilty to making illicit payments to another candidate and covering them up during Gray’s 2010 mayoral campaign.

Federal prosecutors asked the judge not to set a sentencing date because their investigation into corruption in District politics is continuing, and Gore’s attorney did not object. Gore will return to court on Dec. 12.

Gore is one of three former Gray campaign aides to plead guilty to crimes that occurred during the 2010 campaign, in which Gray defeated incumbent Adrian Fenty. The investigation has revealed that Gray’s victory was aided by $650,000 in illicit funds.

Gore likely faces 12 to 18 months in prison

The mayor has not been charged with any crime at this time.
