As Mayor Bill de Blasio continues to get battered with negative headlines regarding his fundraising, he gained a small measure of satisfaction Tuesday regarding a leak of damaging information against him. NY1's Bobby Cuza has more.

Ever since a report from the state Board of Elections (BOE) was leaked last month — a report that found that de Blasio's fundraising on behalf of State Senate Democrats had violated campaign finance law — the mayor's been complaining that it was a political hit job.

Tuesday, he was partially vindicated, as a report from the state inspector general blasted the leak and a lack of coherent policy at the state Board of Elections when it comes to confidential information.

The board's Director of Public Information, John Conklin, admitted to leaking the report to a Daily News reporter and to State Senate Republicans. But Conklin, a GOP appointee, said he essentially acted alone.

That prompted lead investigator Risa Sugarman to say in a statement, "Allegations were made primarily by the New York City mayor that I leaked the report due to political motivations. Now that we know the facts, I hope the mayor will apologize for maligning my integrity and professionalism."

No apology was forthcoming. Instead, the mayor's campaign lawyer, Laurence Laufer, said in a statement, "The IG's [inspector general] report confirms that Ms. Sugarman's office failed to secure the confidentiality of the memo, and raises serious questions about the BOE's management and policies. If anyone should apologize, it is surely the BOE."

Meanwhile, in another apparent document leak, the Daily News detailed an internal spreadsheet that de Blasio's team maintained as he considered appointments to various boards and commissions. It listed donors with notes like "did a lot" and "decent amount."

"There's nothing illegal," longtime political consultant George Arzt said.

Arzt said the problem is one of optics.

"Every administration rewards its supporters," Arzt said. "No one has catalogued a list like I've seen in today's paper."

On a separate front, investigators are reportedly looking into the possibility of illegal donations to de Blasio's 2013 mayoral campaign, through the use of so-called straw donors.

After the news site DNA Info highlighted several unusual donations, the de Blasio campaign said it will return $32,000 in questionable contributions.
