The D.C. Office of Campaign Finance is conducting an audit of Attorney General Karl Racine in connection to illegal campaign contributions during his 2014 campaign.

The OCF is reviewing multiple instances of excess contributions totaling at least $3,500, according to spokesperson Wesley Williams.

The law limits donors to giving $1,500 to attorney general candidates, but groups like Home Depot’s political action committee and AT&T reportedly gave more than that amount during Racine’s election run, according to NBC Washington, which flagged the illegal contributions.

Racine, the District’s first elected attorney general, has long been rumored to be considering a run against Mayor Muriel Bowser in next year’s mayoral election.

His campaign findings come two months after the OCF ordered Bowser’s campaign committee to pay a $13,000 fine after finding more than a dozen campaign contributions over the legal limit.

The finance office also fined Ward 4 Councilmember Brandon Todd $5,100 in June for “irresponsible record keeping” during his 2015 special election campaign.

The AG’s spokesperson Marrisa Geller told DCist that the office cannot comment on anything campaign-related.

Since the findings, NBC Washington reports that Racine refunded Home Depot $1,500 and AT&T $250, in addition to refunding three individual donors.

During her investigation, Bowser’s campaign voluntary refunded the excess funds as well.

There are several campaign finance bills currently before the D.C. Council. Racine drafted one of them himself, a bill that would ban companies for two years from bidding on contracts that are associated with elected officials who they’ve supported financially.

It’s unclear if Racine will have to pay fines for accepting the excess funds as the case remains under review.
